The exact elemental composition of an individual human body depends upon the relative amounts of bone, muscle, fat and other tissues. The body of individual A contains 62.8%H,25.9%O,9.24%C,1.34%N,0.312%Ca, and 0.223% P. Note that those elements compose 99.815 mole percent with the remainder made of numerous elements in smaller quantities. Neglect the trace elements and convert the mole fractions to mass fractions for the top six elements in the body. Hint: by neglecting the trace elements, the sum of your mass fractions should equal 1.00 (or close to it, depending on rounding). Assume the following atomic masses in your calculations: Carry out all calculations in excess of three significant figures; the answers reflect small differences in the exact compositions of individuals.
