Question

What will be the number of molecules of gas occupying 280ml at N.T.P.

Answer 1

Answer:

at NTP volume is 22.4 liter here a gas volume 280ml (0.280lit) , mole = given volume /22.4 , mole of gas =0.280/22.4 then mole is 0.0125 and for no. molecule of gas formula is :: no.of molecule= mole ×avagadro no. ,,,,

no. of molecule of gas = 0.0125×6.022×10^23. then no. of molecule of gas is 0.0752×10^23
