Question

the density of iron is 7.8 g/cm³. then what is the mass of 100 cm³ iron ?​

Answer 1

Answer:

780 g

Step-by-step explanation:

density = mass /volume

Answer 2

$\large\underline{\underline{\sf Given:}}$

• Density of iron = 7.8 g/cm³

• Volume of iron (V) = 100cm³

$\large\underline{\underline{\sf To\:Find:}}$

• Mass of iron (m) = ?

$\large\underline{\underline{\sf Solution:}}$

$\large{\boxed{\sf Density=\frac{Mass}{Volume}}}$

$\large\implies{\sf 7.8=\frac{m}{100}}$

$\large\implies{\sf m=7.8×100}$

$\large\implies{\sf 780g}$

$\large\underline{\underline{\sf Answer:}}$

•°• Mass of iron is 780g.
