Question

The blood has relative density of 1.060,just slightly higher than water. If the average adult blood is 5 L, determine the weight of the blood.

Answer 1

By definition, density is

$\displaystyle \rho = \frac{m}{V}$

So, $m = \rho \cdot V =1.060 \, \frac{g}{cm^3} \cdot5 \cdot 10^3 \, cm^3 = 5.3 \cdot 10^3 \,g = 5.3 \, kg$

Answer: 5.3 kg
