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.
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.
To calculate the molecular weight (MW), you need to find the atomic masses of each element in the compound and sum them up.
Here's how you can calculate the molecular weight of the compound C5H4FeN4:
1. Find the atomic masses of each element:
- Carbon (C): 12.01 atomic mass units (amu)
- Hydrogen (H): 1.01 amu
- Iron (Fe): 55.85 amu
- Nitrogen (N): 14.01 amu
2. Multiply the atomic masses by the respective subscripts in the molecular formula:
- Carbon (C): 5 x 12.01 amu = 60.05 amu
- Hydrogen (H): 4 x 1.01 amu = 4.04 amu
- Iron (Fe): 1 x 55.85 amu = 55.85 amu
- Nitrogen (N): 4 x 14.01 amu = 56.04 amu
3. Sum up all the atomic masses:
60.05 amu + 4.04 amu + 55.85 amu + 56.04 amu = 175.98 amu
Therefore, the molecular weight of the compound C5H4FeN4 is approximately 176 (rounded to the nearest whole number) with no units.
