What is the formula for calculating the pressure of a gas?
Most gases closely follow an equation of state called the ideal gas law,
It's important to pay attention to the units, however. In strict SI units (highly recommended), express n in moles, R is the universal gas constant
The other common set of units is where V is in liters (L) and
0.25 mol of helium gas confined to a 6L vessel at 250K will have a pressure equal to
