please............

the number of electrons present in 18 ml of water at 4 degrees celsius? a)6.023*10^24 b)6.023*10^23 c)4.76*10^21 d)4.76*10^20

equal masses of so2 and o2 are kept in a vessel at 27 degrees celcius. the total pressure of the mixture is 2.1atm. the partial pressure of so2 is

at a given temperature and pressure 20ml of the gas diffuses through a porous membrane in 5 seconds. calculate the volume o carbon dioxide which diffuses in 10 seconds if the vapour density of the gas is 11 a)10√(2) b)20/√(2) c)40√(2) d)10/√(2) correct op...

the gases contain 10^22 and 10^23 molecules present in different vessels at the same temperature. the ratio of their average K.E is the correct answer is 1:1 i think please give explanation
