Assuming 74.2 cm of pressure refers to the mercury column.
Under standard temperature and pressure (273.15°K, 100 kPa=760.06 mmHg),
the gas constant is:
62.364 L mmHg K−1 mol−1
molecular mass of N2=2*14.0067=28.0134
So
volume occupied by 5.25 gram of nitrogen at 26 degree Celsius and 74.2 cm of pressure
=62.364/742*(273.15+26)*(5.25/28.0134)
=4.7 litres
