2. 22. Find the mass of one apple in grams.
Jawaban:
60
Penjelasan dengan langkah-langkah:
Apel = A
jeruk = J
Pisang = P
A+J+P = 170
J + A = 130 berat P = 170 - 130 = 40
A + P = 100 berat J = 170 - 100 = 70
A= 170 - 40 - 70 = 60 grams
3. Calculate the mass in grams: 0.5 mol of oxygen atoms
mass (g) = mol x Ar Oxygen= 0.5 x 16 = 8 gram
4. The total of mass of 40 bottles contents milk is 6kg fin the mass of each bottle content milk(type ur answer in grams!)
Penjelasan dengan langkah-langkah:
6 kg = 6000 gr
So, 6000 gr : 40 = 150 gr
Hence, each bottle of milk weighs 150 gr.
Hope this helps you!
5. A Box with 4 simiral books has a mass of 6.26kg. The mass of the box is 0.5 kg. Find the mass of one book and express your answer in kilograms and grams. HELP
Jawab:
1.44 kg = 1440 grams
Penjelasan dengan langkah-langkah:
The mass of 4 similar books = 6.26 kg - 0.5 kg = 5.76 kg.
The mass of each book = 5.76 kg : 4 = 1.44 kg = 1440 grams
6. What is the maximum mass, in grams, of magnesium oxide that can be formed when 4.8 g of magnesium reacts with oxygen?
Jawaban:
So the maximum mass of magnesium oxide is :
4,8 g + 2,4 g = 7,2 g
Penjelasan:
reacts magnesium with oxygen :
[tex]\boxed{2Mg + O_2 \rightarrow 2MgO}[/tex]
Beacuse mole is equal with mass, so that we can use coefficient comparison :
m O2 = 1/2 x 4,8 g = 2.4 g
So the maximum mass of magnesium oxide is :
4,8 + 2,4 = 7,2 g
7. An empty box has a mass of 46 grams. Jims packs 20 cans of soup into the box. Each can of soup has a mass of 450 grams. What is the total mass of the box of soup?
Jawab:
946 g
Penjelasan dengan langkah-langkah:
Diketahui :
[tex]m^{box}[/tex] : 46 g
can/box : 20
[tex]m^{can}[/tex] : 450
Ditanya :
[tex]m^{box of soup}[/tex] : ?
Jawab :
[tex]m^{box of soup}[/tex] = [tex]m^{box}[/tex] + n([tex]m^{can}[/tex])
= 46 g + 20(450 g)
= 46 g + 900 g
= 946 g
Jadi :
total mass of the box of soup is : 946 grams/0,946 kg
Sorry if im wrong :)

If 1 orange is 110 grams,so the mass of 5 oranges is :
= 110 grams x 5
= 550 grams
9. 100 grams of salt solution contains 20 grams salt .Find mass percentage
mass percentage (w/w) = (grams of salt / grams of solution) x 100
mass percentage (w/w) = (20 gr / 100 gr) x 100
mass percentage (w/w) = 20%
10. the mass of durian is 3.875 g. it is 428 g heavier than papaya. what is the total mass of the 2 fruits. express your answer in kilogram and grams
Jawaban:
3,447 kg and 3.447 g
Penjelasan dengan langkah-langkah:
the mass of papaya = 3.875 - 428 = 3.447 g
in grams = 3.447 g
in kilograms = 3.447 : 1000 = 3,447 kg
11. Bryan had some mangoes and some oranges. The mass of mangoes is 6/5 of the mass of oranges. He gave away 39 grams of mangoes and 15 grams of oranges. He then had twice as much as oranges as mangoes. How many grams mangoes did he have in the end?
Jawab:
In the end, Bryan had 15 grams of mangoes.
Penjelasan dengan langkah-langkah:
The mass of mangoes = x
The mass of oranges = y
The mass of mangoes is 6/5 of the mass of oranges:
x = (6/5) × y
⇔ 5x = 6y (statement 1)
Bryan gave away 39 grams of mangoes:
x – 39 = a
Bryan gave away 5 grams of oranges:
y – 15 = b
He then had twice as much as oranges as mangoes
⇔ He then had oranges twice as much as mangoes
b = 2a
⇔ y – 15 = 2(x – 39)
⇔ 2(x – 39) = y – 15
⇔ 2x – 78 = y – 15
⇔ 2x = y – 15 + 78
⇔ 2x = y + 63 (statement 2)
The question is:
How many grams mangoes did he have in the end?
This is equivalent to: x – 39
Let's try to find x by eliminating y:
2x = y + 63 (statement 2)
5x = 6y (statement 1)
====multiply statement 2 by 6====
12x = 6y + 378
5x = 6y
– ----------------------
7x = 0y + 378
7x = 378
x = 54
In the end:
x - 39 = 54 - 39 = 15
∴ Conclusion: In the end, Bryan had 15 grams of mangoes.
--------------------------------------------------------
Verification
From statement 1, we know that:
y = (5/6)x
If x = 54, then:
y = (5/6)54 = 45
So, in the beginning, Bryan had 54 grams of mangoes and 45 grams of oranges.
After giving away 39 grams of mangoes, he had 15 grams of them.
After giving away 15 grams of oranges, he had 30 grams of them.
Therefore, he had oranges twice as much as mangoes. It could also be said in the way of "he had twice as much as oranges as mangoes".
12. Find the total mass of the watermelon and the bunch of grapes. Express you answer in kilograms and grams.
Penjelasan dengan langkah-langkah:
watermelon = 2,4 kg = 2,4 x 1000 = 2400 g
grapes = 520 g = 520 / 1000 = 0,52 kg
total = 2,4 kg + 0,52 kg
= 2,92 kg
= 2.920 g
13. what is the cocentrasion (in M and mass%) of the resulting solution when you add 5 grams of NaOH to 95 ml water?
M = (gr ÷ Mr) × (1000 ÷ mL)
= ( 5 ÷ 40) × (1000 ÷ 95)
= 1,32
density of water is 1 gr/mL ⇒ 1 = gr ÷ 95 ⇒ gr = 95
mass% = ( mass of solute ÷ (mass of solution)) × 100%
= (5 ÷ ( 5 + 95)) × 100% = 5%

16. The density of aluminium is 2.7 kg/m3. If the mass of aluminium is 8.1 grams, what is the volume of the aluminium in m3?
Jawaban:
[tex]\sf\large{V=0,003\ m³}[/tex]
Penjelasan dengan langkah-langkah:
The known things are;
[tex]\sf\large{ρ = 2,7\ kg/m³}[/tex]
[tex]\sf\large{m = 8,1\ g = 0,0081\ kg}[/tex]
The asked of the volume of aluminium
The answer is;
Use the formula;
[tex]\sf\large{ρ} = \LARGE{\frac{m}{V}}[/tex]
[tex]\sf\large{V} = \LARGE{\frac{m}{ρ}}[/tex]
[tex]\sf\large{V} = \LARGE{\frac{0,0081}{2,7}}[/tex]
[tex]\sf\large{V = 0,003\ m³}[/tex]
So, the volume of the aluminium is [tex]\sf\large0,003\ m³[/tex]
