I'm doing a webassign and i'm so lost! Can anyone provide me with how to find the answers? I don't even know where to begin on these ones. They are gas law problems
If 3.15 mol of argon gas occupies a volume of 100. L at a particular temperature and pressure, what volume does 14.67 mol of argon occupy under the same conditions?
Suppose two 300.0 L tanks are to be filled separately with the gases helium and hydrogen. What mass of each gas is needed to produce a pressure of 155 atm in its respective tank at 22°C?
When calcium carbonate is heated strongly, carbon dioxide gas is released.
CaCO3(s) CaO(s) + CO2(g)
What volume of CO2(g), measured at STP, is produced if 16.5 g of CaCO3(s) is heated?
A gaseous mixture consists of 6.75 g of N2, 4.09 g of O2, and 2.65 g of He. What volume does this mixture occupy at 23°C and 1.45 atm pressure?
Any help with these would be great, my teacher is not ideal. Thanks!!!

PV=nRT. One bit of advice... CHECK THE UNITS. You can find values for the gas constant in many different combinations of units. If you are not using the right value for R (units on R are the same as the units of PVnT), you will NOT get the right answer. Good luck
