PLEASE ANSWER THESE QUESTIONS. USE UNITS. THANKS IN ADVANCE

6- If 18.38 mol of helium gas is at 12.1∘C and a gauge pressure of 0.386 atm .

Part A: Calculate the volume of the helium gas under these conditions.

Part B: Calculate the temperature if the gas is compressed to precisely half the volume at a gauge pressure of 1.06 atm .

7- A storage tank contains 21.6 kg of nitrogen (N2) at an absolute pressure of 3.33 atm .

Part A: What will the pressure be if the nitrogen is replaced by an equal mass of CO2?
