Question

One liter of a gas at STP weight $1.16g$ it can possibly be

• A. $O_2$
• B. $CO$
• C. $C_2{H}_2$
• D. $C{H}_4$

Answer 1

Answer: (C)

$1L$ of gas at STP weight $1.16g$

$\therefore 22.4L$ of gas at $STP$ weight $=2.4\times 1.16=23.984\approx 36$

This molecular weight indicates that given compound is $C_2{H}_2$.
