MCQ
$7.5$ grams of a gas occupy $5.8$ litres of volume at $STP$ the gas is
- ✓$NO$
- B${N_2}O$
- C$CO$
- D$C{O_2}$
✓
Answer
Correct option: A.
$NO$
a
(a) $5.8\,L$ of gas has mass $ = 7.5\,gm$
(a) $5.8\,L$ of gas has mass $ = 7.5\,gm$
$\therefore $ $22.4\,L$ of gas has mass =$\frac{{7.5}}{{5.8}} \times 22.4 = 28.96$
So molecular weight = $29$
So, molecular formula of compound is $NO$
