ANSWER:

Step 1 of 3

According to ideal gas law, the number of moles can be calculated by the following formula.

                                                  ........................(1)

Rearrange the formula(1)

                                                     .......................(2)
                                                     

Here,

P = pressure

V = Volume

n = Number of moles

R = Gas constant

T = Temperature.
