A compound with an empirical formula of C 2H 4Br has a molar mass of 215.90 g/mol. What is the molecular formula?

We need to find the value of C2 H4 Br = ?

Here,

C = 12 \frac{"grams"}{"mol"}

H = 1 \frac{"grams"}{"mol"}

Br = 80 \frac{"grams"}{"mol"}

x \times (24 + 4 + 80) = 216

x \times 108 = 216

x= 2

Thus, the value of C4 H8 Br = 2
