PLZ HELP as soon as possible plz answer all 4 of the questions If PV = nRT, then if I increase the amount of moles of a gas in a glass jar,

and the temperature of the gas stays the same,

and volume of a jar obviously stays the same,

what will happen to pressure inside the jar?

Question 1 options:

Pressure will decrease.

We can not be sure.

Pressure will increase.

Which of the following is NOT equal to PV = nRT

Question 2 options:

R = PV/nT

n = PVT / R

P = nRT / V

V = nRT/P

PV= nRT

Given that R = 8.31 L x kPa / K x mol,

if 1.5mol of a gas is in a 10.0L container at 250K, what is the pressure of the gas?

Question 3 options:

3750 kPa

0.49 kPa

3,200 kPa

311.6 kPa

PV= nRT

Given that R = 8.31 L x kPa / K x mol,

If 3.0L of a gas is at a pressure of 225 kPa, at 315 K temperature, then how big is the container trapping this gas?
