An open flask sitting in a lab fridge looks empty, but we know that actually it is filled with a mixture of gases called air. if

OLga [1]

Use ideal gas law PV=nRT
at STP, pressure is 1atm and temperature is 273K (0 Celsius)
1×1.5L=n × 0.0821 × 273
n is moles and R is ideal gas law constant, always 0.0821
moles= 14.9422(6.02×10^23 molecules)=9.0×10^24 molecules
