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

Step-by-step 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* 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}}=(50)/(22.4)=2.23moles`

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