Look up the atolmic masses of each element, multiply by the number of atoms of that element, then add everything.
For example, H2O is
2*1.008 = 2.016
1*16 = 16
Total molecular weight is 18.016. That is 18 to the nearest whole number.
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.
