mols C = 7.961/44 = ?
mols H = 1.164 x (2/18) = ?
mols N = 1.551/30 = ?
Now find the ratio in small whole numbers to one another. The easy way to do that is to divide the smallest number by itself (which gives you 1.000), then divide the other numbers by the same small number. Round to whole number to find CxHyNz. Post your work if you have trouble.
A sample of a substance (containing only C, H, and N) is burned in oxygen.
7.961 g of CO2, 1.164 g of H2O and 1.551 g of NO are the sole products of combustion.
