1.

The mass aof 350cm^(3) of a diatomic gas at 273 K at 2 atmospheres pressure is one gram. Calculate the mass of one atom of the gas.

Answer»


Solution :(i) Find the volume of the gas at STP which on CALCULATION comes out to be `700cm^(3)`
(ii) Find the mass of 1 mole, i.e, 22.4 L of gas at STP, i.e., `(22400)/(700)=32g`
(III) Calculate the mass of one molecule, i.e., `(32)/(6.022xx10^(23))G` and divide it by 2 to get the mass of one atom of the gas.
