Question

Calculate the amount of moles in 6.75 liters of nitrogen gas.

151 mol
.301 mol
8.44 mol
0.0215 mol

Answer 1

Answer:

There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.

Explanation:

Given,

Volume of N2 gas = 6.75 L

We know,

At STP,

Number of moles = $\frac{Volume}{22.4 L}$   [Here 22.4 liter is the molar volume of any gas at STP]

                              = $\frac{6.75L}{22.4L}$

                              = $0.301$

∴There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.
