Calculate the molecular weight (MW) of a compound with the molecular formula C5H

Question

Calculate the molecular weight (MW) of a compound with the molecular formula C5H4FeN4. Report your answer to the nearest whole number value and do not include units. For example, if the MW was 35.45 amu, you would report "35" as your answer. (hint: don't worry that in round to the nearest whole number you won't have the proper number of sig figs in your answer. Just worry about the correct answer, and report it as a whole number. At the same time, never round your answers until you're finished with your calculations. It's an easy mistake to make, and a simple way to turn a "right" answer into a "wrong" answer.)

Explanation / Answer

Molecular weight of C is - 12.01 g/mol
Molecular weight of C is H- 1.01 g/mol
Molecular weight of C is Fe - 55. 933 g/mol
Molecular weight of C is N - 14 g/mol

=(5 x C) + (4 x H) + (1 x Fe) + (4 x N) = 176.023 g /mol

The nearest whole number is 176.
