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, 26.0% O, 9.22% C, 1.34% N, 0.313% Ca, and 0.223% P. Note that those elements compose 99.896 mole percent with the remainder made of numerous elements in smaller quantities. Part 1: 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: H: 1.00794 O: 15.999 Ca: 40.078 C: 12.0107 N: 14.0067 P: 30.972762 Part 2:

Help with the following question.
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, 26.0% O, 9.22% C, 1.34% N, 0.313% Ca, and 0.223% P. Note that those elements compose 99.896 mole percent with the remainder made of numerous elements in smaller quantities. Part 1: 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: H: 1.00794 O: 15.999 Ca: 40.078 C: 12.0107 N: 14.0067 P: 30.972762 Part 2: Assume that the mass of the body is 80.0 kg. Calculate the mass (kg) and number of moles (kmol) of oxygen in the body. Part 3: For the same individual of mass 80.0 kg, calculate the total number of kilomoles of the top six elements in the body. Note that you do not need to break out the number of kmol of each element, just the total number.
