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
