1. What is the volume in liters (L) of 2 moles of an ideal gas at 25°C and 790 mmHg? (remember that temperature must be expressed first in Kelvin) 2. Assuming that a 1.5 g gas occupying a volume of 500 mL at a pressure of 2.5 atm and a temperature of 75°C is behaving like an ideal gas. What is the molecular weight (in g/mol) of the gas?

As you approach the Gas laws, perform the following problems using the equation PV= nRT provided in the presentation remember that n (number of moles) can be further derived as n= g/ MW (molecular weight) then solve the 2 problems below, the final answer should be rounded off to 2 decimal places (e.g. 2.678 L rounded off to 2.68 L) use the gas constant  R= 0.08205 L- atm/mole-K.
