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

If 200 mL " of " N_(2) " at " 25^(@)C and a pressure of 250 mm are mixed with 350 mL " of " O_(2) " at " 25^(@)C and a pressure of 300 mm so that, the volume of resulting mixture is 300 mL , what would be the final pressure of the mixture at 25^(@)C ?
