Question

the sample contains 0.624 mol c, 1.248 mol h, and 0.078 mol o. determine the empirical formula for the hydrocarbon. what is the subscript for c? c?ho hint: \divide by smallest\

Explanation:

Step1: Identify the smallest mole value

The moles of C, H, O are 0.624 mol, 1.248 mol, 0.078 mol respectively. The smallest is 0.078 mol (O).

Step2: Divide moles of C by smallest mole

Moles of C: 0.624 mol. Divide by 0.078 mol: $\frac{0.624}{0.078} = 8$.

Answer:

8
