If 200mL of He at 0.66 atm and 400 mL of `O_(2)` at 0.52 atm pressure are raised in 400 mL vessel at `20^(@)C` then find the partial pressures of He and `O_(2)` ?

What will be the partial pressures of He and O_(2) respectively if 200 ml of He at 0.66 atm pressure and 400 ml of O_(2) at 0.52 atm pressure are mixed in 400 ml vessel at 20^(@)C ?

A gaseous mixture containing 8g of O_(2) and 227 mL of N_(2) at STPis enclosed in flask of 5 L capacity at 0^(@)C . Find the partial pressure of each gas and calculate the total pressure in the vessel.

Equal weight of N_(2) and O_(2) are put in a flask at 27^(@)C Calculate the partial pressure of N_(2) if partial pressure O_(2)=0.44 atm.

What is partial pressure? If the total pressure of a mixture of 4 gm H_2 & 16 gm O_2 at 27^@C be 5 atm. find the ratio of partial pressure . of H_2 & O_2

A balloon contains 500m^(3) of He at 27^(@)C and 1 atm pressure. Then , the volume of He at -3^(@)C and 0.5 atm pressure will be
