Question

Determine the empirical formula for the compound that contains 55.0 g carbon and 294 g sulfur

Answer 1

Convert g to moles.

55/12.01 = ?? moles C
294/32.066 = ?? moles S
Find the ratio of the two elements to each other. The easy way to do that is to divide the smaller number by itself (getting 1.00 for that elements). Then divide the other number by that same small number. Round to whole numbers and that will give you the formula.
