How many moles of oxygen gas, o2, are in a storage tank with a volume of 1.000×105 l at stp?

Explanation:

Ideal gas law states that the product of pressure and volume is directly proportional to the absolute temperature and gas constant.

Mathematically,          PV = nRT

where,         P = pressure

                   V = volume

                   n = number of moles

                  R = gas constant

                  T = temperature

At STP (Standard temperature and pressure) the value of temperature is 273 K and pressure is 1 atm.

Therefore, calculate moles of oxygen as follows.

                         PV = nRT

or,              

                            =  

                            =

                            = mol

Thus, we can conclude that there are moles of oxygen gas are in the storage tank.
