Question

A piece of iron weighs156g and has a volume of 20cm³. Find the density of iron.​

Answer 1

Answer:

7.8 g/m³

Explanation:

$mass \: of \: the \: iron \:, \: \: \\ m \: = \: 156 \: g \\ volume, \: v \: = \: 20m^{3} \\ \\ density, \: p \: = \frac{156}{20} \\ \\ p \: = \: 7.8 \: g/m {}^{3}$
