Guys I found this site which I consider is amaizing because every time you go in you get different examples.
Is Like a quiz and it can help you to study....
Enjoy.
God Bless you.

Charles’s Law Problems
1) A container holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg.
What will be its volume if the temperature increases by 35° C?
2) A sample of oxygen occupies a volume of 160 dm3
at 91° C. What will be
volume of oxygen when the temperature drops to 0.00° C?
3) A sample of hydrogen has an initial temperature of 50.° C. When the
temperature is lowered to -5.0° C, the volume of hydrogen becomes
212 cm3
. What was the initial volume of the hydrogen in dm3
?
4) 568 cm3
of chlorine at 25° C will occupy what volume at -25° C while the
pressure remains constant?
5) A sample of helium has a volume of 521 dm3
at a pressure of 75 cm Hg and
a temperature of 18° C. When the temperature is increased to 23° C, what is
the volume of the helium?

Boyle’s Law Problems
1) A container holds 500. mL of CO2 at 20.° C and 742 torr. What will be the
volume of the CO2 if the pressure is increased to 795 torr?
2) A gas tank holds 2785 L of propane, C3H8, at 830. mm Hg. What is the
volume of the propane at standard pressure?
3) A balloon contains 7.2 L of He. The pressure is reduced to 2.00 atm and the
balloon expands to occupy a volume of 25.1 L. What was the initial pressure
exerted on the balloon?
4) A sample of neon occupies a volume of 461 mL at STP. What will be the
volume of the neon when the pressure is reduced to 93.3 kPa?
5) 352 mL of chlorine under a pressure of 680. mm Hg are placed in a container
under a pressure of 1210 mm Hg. The temperature remains constant at
296 K. What is the volume of the container in liters?
