The resultant moles of nitrogen gas that are present in the container is 2.96 moles.
<h3>How do we convert mass into moles?</h3>
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
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.
