Determine the number of moles of oxygen gas in the following

Determine the number of moles of oxygen gas in the following container.

The container holds 0.55 m³ at 75.78^oF and an a gauge pressure of 35.34kPa.

Solution

Given data

                  v =0.55m^3

                   p=35.34kpa

                    T =75.78F =297.4k

Formula

                   n =pv/RT

                   n =35.34*055/0.0821*297.4

                      =0.796 moles
