The human body contains 63% H, 25.5% O, 9.45% C, 1.35% N, 0.31% Ca and 0.22% P, plus trace elements present in smaller quantities. Are these mole or mass percents? How many grams of each element are present in a 5-kg baby? What is the mass of deuterium in the baby if deuterium naturally constitutes about 0.014% of all hydrogen atoms?
