Answer to Question #278664 in Physics for ZAR

Question

Biological Tissues are typically made up of 98% water.Given that the density of water is 1.0x10^-3 kg/m3. Estimate the mass of a heart of a young man.

b: mass of a cell with a diameter of 0.5 x 10^-6 m

Answer 1

The mass of a heart of a young man is 300 g.

The mass of the cell is

$$m=\rho ·\frac 43\pi r^3=5.24·10^{-16}\text{ kg}.$$
