So, in class my teacher gave us a lab to do. Its called It's a crash test, dummy. Anywho, the lab asked us to find the amount of acetic acid and sodium bicarbonate. We are allowed to use Trail and Error or Stio, or Ideal gas law.
This lab is about finding the amount of the above mixtures placed in a ziplock sanwhich bag and see if it protects the raw egg from a 2meter fall.
Right now Im so confused because im lost on the calculations. The volume of my bag is 709__. I do not know the unit[Please help with that] :). So for the calulations, How do I find the moles and all the other good stuff? I know we use Pv=nRT or Pv/Rt=N, but the mole turns out to be a weird number..
Please help.

One mole of an ideal gas at STP occupies 22.4 liters.
I got the above by googling. In any case STP would be defined by which units are used in the constant you are using in the ideal gas formula.
pv=nRt
