The weight of  a man is 690N which contains 5.3 x 10-3 m3 of blood. Find blood's weight. Take density of blood as kg/m3

Given:  Volume of the blood present in the body,V = 5.3 x 10-3 m3 = 0.0053 m3

 density of blood blood cells,ρ = 1125 kg/m3

Weight of the blood = mass of the blood volume × g

 = ρ V g = 1125x0.0053x9.8 =58.49N
