14. A sample containing a mixture of Oz, N2, H2 gases has a volume of 42.0 L and is held at a temperature of 301 K. If the total pressure of the sample is 104 kPa and the partial pressures of
N2 and H2 are 60.0 kPa and 28 kPa respectively, calculate the number of moles of Oz that there
are in the sample. *
Could someone answers this please :)))
