alleryFor a gas at NTP, the number of moles is given by
A$\dfrac{\text{Volume in litres}}{11.2}$
B$\dfrac{\text{Volume in litres}}{22.4}$
C$22.4 \times \text{Volume in litres}$
D$\dfrac{\text{mass in grams}}{22.4}$
Answer & Solution
Correct answer: B. $\dfrac{\text{Volume in litres}}{22.4}$
The formula sheet states that for gases at NTP, number of moles $= \dfrac{\text{Volume in litres}}{22.4}$.
This is the molar volume relation used here.
