Pressure and Volume Problems: Solve the following problems. Assume temperature and amount of gas remain constant.

I NEED HELP WITH THIS PART I ALREADY KNOW THE ANSWER AND WILL PROVIDE IT DOWN BELOW>>>>

P1V1= P2V2
If 22.5 L of nitrogen at 0.95 atm are compressed to 1.35 atm at constant temperature, what is the new
volume?
V2 = 15.84 L

The standard emf for the cell using the overall cell reaction below is +2.20 v: 2al(s) + 3i2(s) → 2ai3+(aq) + 6i-(aq) the emf generated by the cell when [ai3+] = 3.5 × 10-3 m and [i-] = 0.015 m is v. the standard emf for the cell using the overall cell reaction below is +2.20 v: 2al(s) + 3i2(s) 2ai3+(aq) + 6i-(aq) the emf generated by the cell when [ai3+] = 3.5 × 10-3 m and [i-] = 0.015 m is v. 2.36 2.24 2.21 2.51 2.04
