Solve the all parts of given question:
Question: A physics lecture room has a volume of 237 m3. For a gas pressure of 1.00 atm and a temperature of 26.0 oC,
Part A: Use the ideal gas law to estimate the number of air molecules in the room.
Part B: Assume all the air is N2. Calculate the particle density that is, the number of N2 molecules per cubic centimeter.
Part C: Calculate the mass of the air in the room.
I need the right answer and steps of solving this problem. Thanks!
