Question

If the molar mass of a compound is 78. 12 g and the empirical formula is ch, what is the value of the integer that relates the empirical formula to the molecular formula?.

Answer 1

C6H6

Step-by-step explanation:

The empirical formula, CH, has a unit mass of 13 (12+1). 78/13 = 6

There are 6 units of CH in the intact compound. The molecular formula must be C6H6.

C: 6 * 12 = 72

H: 6 * 1 = 6

Total = 78
