How do you find the molar volume of hydrogen gas?

Answer 1

Natalie Anton

Using the Ideal Gas Law, you would find the volume of 1 mole of a gas at Standard Temperature and Pressure (STP).

STP = 1 atm of pressure and 273 K for temperature

P = 1 atm
V = ???
n = 1 mole
R = 0.0821 atm L/mol K
K = 273 K

#P V = n R T #
solves to
#V = (n R T )/ P#

#V = (1 mol (0.0821 (atm L))/(mol K) 273 K)/(1 atm)#

V = 22.41 L of gas @ STP
This is also known as Avogadro's number for molar volume of a gas @ STP

I hope this was helpful.

To find the molar volume of hydrogen gas, you can use the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature. Rearrange the equation to solve for volume (V) by dividing both sides by the number of moles (n). The resulting equation will be V = (nRT) / P. Then, plug in the values for pressure, number of moles, ideal gas constant, and temperature to calculate the volume.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
