Question

A piece of iron has density 2.5 mg/cm3 and volume is 10 cm3 , find mass of given piece of iron in

(a) S.I unit (b) C.G.S. unit.( The 3 with cm means square)​

Answer 1

Answer:-

• Density=2.5mg/cm^3
• Volume=10cm^3

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Mass=Density\times Volume$

$\\ \sf\longmapsto Mass=2.5\times 10$

$\\ \sf\longmapsto Mass=25mg$
