Sagot :
The resultant moles of nitrogen gas that are present in the container is 2.96 moles.
How do we convert mass into moles?
Mass of any substance will be converted into moles by using the below equation as:
n = W/M, where
- W = given mass of nitrogen gas = 50g
- M = molar mass of nitrogen gas = 28 g/mol
- n = 50 / 28 = 1.78 moles
From the ideal gas equation of gas we know that moles and volume is directly proportional to each other and for this question equation becomes,
V₁/n₁ = V₂/n₂, where
- V₁ & n₁ are the initial volume and moles of gas
- V₂ & n₂ are the final volume and moles of gas.
On putting all values, we get
n₂ = (5L)(1.78mol) / (3L) = 2.96 moles
Hence required moles of nitrogen gas are 2.96.
