Question

Find the mass of 555cm3 of iron in kg when density of iron is 7.6g/cm3

Answer 1

Answer:

Mass of iron = 4.218 kg

Explanation:

We know that,

Density = Mass/Volume

ρ = M/V

Hence,

Mass = Density * Volume

M = ρV

Given that,

Density = ρ = 7.6 g/cm³

Volume = V = 555cm³

Therefore, putting all the values in we get,

Mass = Density * Volume

M = ρV

M = 7.6 * 555

M = 4218 g

M = 4.218 kg
