answer and explanation

we are asked to determine the number of mols of Oxygen in the sample and we can do this using the ideal gas equation

PV = nRT

and when we rearrange the equation to make n subject of the formula, we gent :

n = PV/RT

= (3.21atm x 47.6L) / (0.0821 x 285K)

= 152.796 / 23.3985

= 6.53 mols
