A compound having the empirical formula ...

A compound having the empirical formula `(C_(3)H_(4)O)_(n)` has a molar mass of `170 +- 5`. The molecular formula of this compound is

A

`C_(3)H_(4)O`

B

`C_(6)H_(8)O_(2)`

C

`C_(6)H_(12)O_(3)`

D

`C_(9)H_(12)O_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`E.F. = C_(2)H_(4)O`
E.F. mass `= 12xx3+4xx1+16 = 56`
`n = (170+-5)/(56)~~3`
`:. M.F. = (C_(3)H_(4)O)_(3) = C_(9)H_(12)O_(3)`
