Question: how to find molar mass of ammonium carbonate?
Answer: Multiply the formula mass of each individual atom by the total number of atoms present. Add up the formula mass together, therefore, it will give you the overall formula mass of (NH)4CO3 . 28.0 + 8.0 + 12.0 + 48.0 = 96.0 g/mol is the formula mass of (NH)4CO3 .
