To calculate the formula mass of Na3NO2, we need to add the atomic masses of each atom in the compound. Na (sodium) has a mass of 22.99 g/mol, N (nitrogen) has a mass of 14.01 g/mol, and O (oxygen) has a mass of 16.00 g/mol. Therefore, the formula mass of Na3NO2 = 3(Na) + 1(N) + 2(O) = 3(22.99) + 14.01 + 2(16.00) = 85.97 g/mol.

The formula mass of H2O (water) is calculated by adding the atomic masses of the elements present in the compound. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1 and 16, respectively. Therefore, the formula mass of H2O is 1 (atomic mass of H) * 2 (number of hydrogen atoms) + 16 (atomic mass of O) = 18.
The molar mass of lithium oxide (Li2O) is calculated by adding the molar masses of lithium (Li) and oxygen (O). Molar mass of Li = 6.94 g/mol Molar mass of O = 16.00 g/mol Molar mass of Li2O = 2*(molar mass of Li) + molar mass of O = 2*(6.94) + 16.00 = 14.88 + 16.00 = 30.88 g/mol
