Two gases oxygen and nitrogen both of volumes 1dm*3 and 3.6dm*3 respectively. and mixed in a container. if the total pressure exerted by the mixture is 300pa. calculate the partial pressure of the two gases

we need the questions , i may then you.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

i think is conclusions.i think so
