Question

. How many moles of ammonia gas, NH3, are required to fill a volume of 50 liters at STP?

Answer 1

in STP every 22.4 litters is 1 mol

Answer 2

Answer:2.23 moles

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass , occupies 22.4 Liters at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given volume}}{\text{Molar volume}}=\frac{50}{22.4}=2.23moles$

Thus 2.23 moles of ammonia gas are required to fill a volume of 50 liters at STP.
