Question

0.2-mole of saturated hydrocarbon x on complete combustion produces 26.4.
CO2. Find the molecular weight of the x is​

Answer 1

=44gm

Explanation:

x+O2→H2O+CO2

mass of C is 26.4g of

CO2=26.4×12/44=7.2gc

2 moles of x = 0.6 moles of C.

We get.

X=CC3H (proper)

Hence,

=44gm(molecular)
