Best ResponseYou've already chosen the best response.1N2O You must make sure that you first count the #atoms for each element in your formula. The elements we have N O Now there are 2 nitrogens and one Oxygen N =2 O = 1 We need the molar mass of each because we need to multiply the number of atoms by the molar mass. N = 14g/mol x 2 atoms = 28 g O = 16g/mol x 1 atom = 16 Assume now that one mole of the sample contains 28g of nitrogen and 16 grams of oxygen. What we do now is add the total 28+16 = 44g in N2O This is like any percent composition formula we take the number of grams of N and put it over the total: We have 28 grams of N Our total is 44 grams of N2O It becomes 28/44% of N And 16/44 % for N2O
