Question

The density of a sample of aluminum is 2.70 g/cm3. You submerse a sample of aluminum in water, and the volume of the water rises 1.3 L (1.3 L is displaced by the aluminum). Using the correct number of significant figures, what is the mass of the sample?

Answer : -

Given:-

Density=2.70

Volume=1.3 L

Mass=?

Using the formula

${\bf{Density={\frac{Mass}{Volume}}}}$

2.70=${\frac{Mass}{1.3}}$

2.70×1.3=Mass

Mass= 3.51 kg
