What is the molar mass of ammonium carbonate?
Let's start off with the chemical formula of ammonia carbonate, which is
Now, we can determine the molar mass of this ionic compound by using the following equation:
atomic weight of element
First, you want to have a periodic table available so you can determine the atomic weight of N, H, C, and O:
- N has a molar mass of 14.01 g/mol
- H has an atomic weight of 1.008 g/mol
- C has an atomic weight of 12.01 g/mol
- O has an atomic weight of 16.00 g/mol
From the chemical formula, we have 2 nitrogen atoms. Therefore, the atomic mass has to be multiplied by 2 to obtain an atomic weight of 28.02 g/mol.
There are 8 hydrogen atoms, so the atomic mass has to be multiplied by 8, which gives you a value of 8.064 g/mol
Next, you have 1 carbon atoms, so the atomic mass of C is 12.01 g/mol
And, there are 3 oxygen atoms, so the atomic mass has to be multiplied by 3, which gives you a value of 48.00 g/mol
Now you want to add the mass of each atom together to obtain the formula mass of the entire compound:
