Question

Calculate the mass (in g) of 0.8 cm³ of steel. The density of steel is 7.8 g/cm³. Give your answer to 2 decimal places.

Answer 1

mass= density times volume so 7.8 g/cm3 by0.8 cm3 answer is 6.24 g and it's already in two decimal places

Answer 2

Answer:

$\boxed{6.24g}$

Explanation:

→ Utilise the density formula

Density = Mass ÷ Volume

→ Rearrange to make mass the subject

Mass = Density × Volume

→ Identify the density and volume values

Density = 7.8 and Volume = 0.8

→ Substitute the values into the density equation

Mass = 7.8 × 0.8 = 6.24 g
