A bar of gold has a mass of 3,8 kg. If the density of gold is 19 g/cm3, what is the volume of the gold?
1. A bar of gold has a mass of 3,8 kg. If the density of gold is 19 g/cm3, what is the volume of the gold?
Penjelasan:
so, the bar of gold has a mass : 3,8 kg ⇒ 3800 g
and the density of gold is : 19 g/cm³
this is the formula : Volume = mass / density
V = 3800 g / 19 g/cm³
V = 200 cm³
the answer is : V = 200 cm³
2. An alloy is made by combining 900 g of copper with 400 g of iron. If the densityof copper is 9 g/cm and density of iron is 8 g/cm', what is the density of the alloy?(assume that the volume of each metal does not change during mixing.)
ρ(cop) = 9 gr/cm³
ρ(iron) = 8 gr/cm³
ρ = m/Vol
Vol = m/ρ ~ constant!
ρ' = ρ(cop) + ρ(iron)
= 9 + 8
= 17 gr/cm³ ~ 17 × 10³ kg/m³ ✓✓
3. If 5 litres of a liquid has a mass of 850 g what is the density of the liquid in g/cm³
Jawaban:
0,17 g/cm^3
Penjelasan:
mass = 850 g
volume = 5 litres = 5.000 cm^3
density = mass/volume
= 850/5.000
= 0,17 g/cm^3

8. 1. A cube has length of 7 cm a width of 8 cm and a height of 2 cm. What is its volume? 2. The density if aluminum is 2.7 g/ml. If the aluminum has a volume of 20 ml, what is the mass of the aluminum? 3. A marble has a volume of 20 ml. It also has a mass of 10g. Calculate the density of the marble. Tolong sertakan cara mengerjakannya
1. its volume = 7 × 8 × 2
= 112 cm
2.mass = the density × volume
= 2,7 g / ml × 20 ml
= 54 gram
3.the density= mass / volume
= 10 / 20
= 0,5 g / ml

14. A cube of copper has a mass of 600kg. copper has a density of 9.3g/cm³. Calculate the length of each side of the cube to the nearest mm.
This is how you solve it
volume = 600.000 / 9,3 (we make 600 kg to 600.000 g because the density use gram to)
Volume = 64.516 cm³ (approximately)
Lenght = 254 cm
Lenght = 254,0 mm
15. A measuring cylinder has a mass of 120 g when empty. When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is 160 g. What is the density of the liquid?
Mass of cylinder (empty) = 120 gram
Mass of cylinder (with liquid) = 160 gram
Volume of liquid = 50 cm³
Density of the liquid (ρ) = ?
Answer:
Find the mass of liquid
With liquid - Empty
= 160 gram - 120 gram
= 40 gram
So, the mass of the liquid is 40 gram
Find the density of the liquid
[tex]\rho=\frac{mass}{Volume} \\\rho=\frac{40\ gr}{50\ cm^3} \\\rho=\frac{40}{50}\ gr/cm^3 \\\rho=\frac{4}{5}\ gr/cm^3 \\\boxed{\rho = 0,8\ gr/cm^3}\\or\\\boxed{\rho = 800\ gr/cm^3}\\[/tex]
