# What is the formula mass for #Sr(NO_3)_2#?

First, you want to have a periodic table available so you can determine the atomic weight of Sr, N, and O:

From the chemical formula, we have 1 strontium atom, so the atomic weight of Sr is just 87.62 g/mol.

There are 2 nitrogen atoms, so the atomic mass has to be multiplied by 2, which gives you a value of 28.02 g/mol

Next, you have 6 oxygen atoms, so you would multiply the atomic mass of O by 6 to obtain an atomic weight of 96.00 g/mol

Now you want to add the mass of each atom together to obtain the formula mass of the entire compound:

To calculate the formula mass of Sr(NO₃)₂, you need to find the atomic masses of each element in the compound and then multiply them by the respective subscript in the formula.

Sr: 1 atom * 87.62 g/mol = 87.62 g/mol N: 2 atoms * 14.01 g/mol = 28.02 g/mol O: 6 atoms * 16.00 g/mol = 96.00 g/mol

Total formula mass = 87.62 g/mol + 28.02 g/mol + 96.00 g/mol = 211.64 g/mol
