Question

A globe of steel has a mass of 12 g and a volume of $15.2c{m}^3$. Find its relative density wrt water.

• A. 0.25
• B. 0.79
• C. 1.25
• D. 1.56

Answer 1

Answer: (B)

0.79

Density (${\rho }_s$) = $\frac{mass\left(m\right)}{volume\left(V\right)}$

Relative density of steel with respect to water=$\frac{{\rho }_s}{{\rho }_w}$

$=\frac{m/V}{{\rho }_w}$

$=\frac{12/15.2}{1}$

$=\frac{12}{15.2}$

$=0.79g/c{m}^3$
