1. What is the volume in milliliters (mL) of 3 moles of an ideal gas at 45°C and 820 mmHg? (remember that temperature must be expressed first in Kelvin) 2. Assuming that a 4 g gas occupying a volume of 890 mL at a pressure of 2.5 atm and a temperature of 65°C is behaving like an ideal gas. What is the molecular weight (in g/mol) of the gas?

Question
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.
