What is the empirical formula of a compound that contains 40 percent carbon, 6.7 percent hydrogen, and 53.3 percent oxygen by mass?

The empirical formula is CH2O bc you divide the percent and the mass of the element, Carbon 40/12.01=3.33, Hydrogen 6.7/1.01=6.63, Oxygen 53.3/16.00=3.33, then divide the lowest number which is 3.33 to all Carbon 3.33/3.33=1, Hydrogen 6.63/3.33=1.99 but rounds to 2, Oxygen 3.33/3.33=1

Iam not going to tell you
