Section 3
Ideal Gas Law
What is the ideal gas law?
Describe when you might want to use the ideal gas law.
How many moles of hydrogen, $\mathrm{H}_{2},$ gas are contained in a volume of 2 $\mathrm{L}$ at 280 $\mathrm{K}$ and 1.5 $\mathrm{atm} ?$
What volume would 1.5 $\mathrm{mol}$ of nitrogen, $\mathrm{N}_{2},$ gas occupy at standard temperature and pressure?
Find the pressure of 3.40 $\mathrm{mol}$ of gas if the gas temperature is $40.0^{\circ} \mathrm{C}$ and the gas volume is 22.4 $\mathrm{L}$
How many moles of helium, He, gas are contained in a $10,000$ L weather balloon at 1 atm and $10^{\circ} \mathrm{C} ?$
Suppose you have 1.0 mol of gas molecules in 22.4 $\mathrm{L}$ at STP. Describe three ways you can get a gas pressure of 0.50 atm.
Will the pressure of helium, He, gas be the same as the pressure of oxygen, $\mathrm{O}_{2},$ if youhave 1 mol of each gas, each at a volume of 22.4 $\mathrm{L}$ and each at 273 $\mathrm{K} ?$ Explain your thinking.
