Question

You fill a balloon with 2.50 moles of gas at 22°C at a pressure of 1.62 atm. What is the volume of the balloon? ​

Answer 1

Use the ideal gas law:

$PV=nRT$

$(1.62\,\mathrm{atm})V=(2.50\,\mathrm{mol})\left(8.314\dfrac{\rm J}{\mathrm{mol}\cdot\mathrm K}\right)(295.2\,\mathrm K^\circ)$

$\implies V=37.34\,\mathrm L$
