Answer
75 grams/mol
Work Step by Step
2 Oxygen atoms, molecular weight of 16 for each atom
2 Carbon atoms, molecular weight of 12 for each atom
5 Hydrogen atoms, molecular weight of 1 for each atom
1 Nitrogen atom, molecular weight of 14 for each atom
Add up the sum of all the molecular weights for every atom in the molecule, and put your answer in grams, this will yield the molar mass of the molecule.
