If the density of blood is 1.060 g/mL what is the mass of 6.56 pints of blood (1 L = 2.113 pints)

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is symmetrical : )
