Question

Determine the molecular formula of the following: Molar

mass of compound equals 78.11 g/mol and an empirical
formula of CH.

NEED HELP!!

Answer 1

C6H6

Step-by-step explanation:

The molecular formula of a substance can be determined by using the expression:

(CH)n = 78.11g/mol

Where;

C = 12, H = 1

(12 + 1)n = 78.11

13n = 78.11

n = 78.11 ÷ 13

n = 6.008

n = 6

Hence, the molecular formula is as follows:

(CH)6

Molecular formula = C6H6
