A sample of water gas contains $$42\%$$ by volume of carbon monoxide,If the total pressure is 760 mm. the partial pressure of carbon monoxide is?

At same temperature $$N_2O_4$$ is dissolved to 40% and 50% at total presure $$p_1$$ and $$p_2$$ atm respevtively in $$NO_2$$.Then the ratio of $$P_1$$ &$$P_2$$ is?

 For the adiabatic expansion of an ideal gas

The vapour pressure of pure benzene at a certain temperature is 200 mm Hg. At the same temperature the vapour pressure of a solution containing 2 g of non volatile non electrolyte solid in 78 g of benzene is 195 mm Hg. What is the molecular mass of solid?

One atmosphere is numerically equal to approximately?

A spherical balloon of $$21\ cm$$ diameter is to be filled up with $$H_2$$ at $$NTP$$ from a cylinder containing the gas at $$20\ atm$$ at $$27^{\circ}C$$. The cylinder can hold $$2.82$$ litre of water. The number of balloons that can be filled up

In a gaseous mixture at $$20^o C$$ the partial pressure of the components are:
$${ H }_{ 2 }$$ : 150 Torr      $${ CH }_{ 4 }$$ : 300 Torr     $${ CO }_{ 2 }$$ : 200 Torr        $${ C }_{ 2 }{ H }_{ 4 }$$ : 100 Torr

$$200\ ml$$ of $$He$$ at $$0.66\ atm$$ pressure and $$400\ ml$$ of $${ O }_{ 2 }$$ at $$0.52\ atm$$ pressure are mixed in a $$400\ ml$$ vessel at $${ 25 }^{ \circ  }C$$. The partial pressure of $$He$$ and  $${ O }_{ 2 }$$ will be:
