mols N = 0.606/14 = about 0.043
mols O = 1.39/16 = about 0.087
Now find the ratio. The easy way to do that is to divide each number by the smaller number.
N - 0.043/0.043 = 1.00
O = 0.087/0,043 = 2.02 and rounds to 2. It may come out a little closer if you do the calculations more accurately.
The molar mass of a compound is 92 g/mol. What is the molecular formula for a sample containing 0.606g Nitrogen and 1.390g Oxygen?
