Question

Calculate the volume of the following gas sample at STP. 4.1 mol N2

Answer 1

We know that:

- number of moles of the gas: 4.1 mol

And we must calculate the volume as sample at STP.

We need to use that

Now, we must use the ideal gas equation

`PV=nRT`

Since we need the volume we must solve the equation for V

`V=(nRT)/(P)`

Finally, we must replace the values in the formula

`V=\frac{4.1mol\cdot0.08206\frac{L\cdot\text{atm}}{k\cdot\text{mol}}\cdot273.15k}{1\text{atm}}`

Simplifying,

`V=91.9002L`

ANSWER:

Volume = 91.9002 L
