The compound that contains 5.4 mol C, 7.2 mol H, and 1.8 mol N has the empirical formula C₃H₄N.
A compound contains 5.4 mol C, 7.2 mol H, and 1.8 mol N. To find the empirical formula, that is, the integers that are the subscripts for each element, we have to divide all the numbers by the smallest one, i.e. 1.8.
[tex]C: 5.4/1.8 = 3\\H: 7.2/1.8 = 4\\N: 1.8/1.8 = 1[/tex]
The empirical formula is C₃H₄N.
In that way, the compound that contains 5.4 mol C, 7.2 mol H, and 1.8 mol N has the empirical formula C₃H₄N.
