The term mole first used by Ostwald in `1896` refers for the ratio of mass of a substance in `g` and its molecular weight. `1 "mole"` of a gaseous compound occupies `22.4 "litre"` at `NTP` and contains `6.023xx10^(23)` molecules of gas.
The maximum number of atoms present are in:

A

`4 g He`

B

`4 g O_(2)`

C

`4 g O_(3)`

D

`4 gH_(2)O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`He=(4)/(4)N, O_(2)=(4)/(32)N,`
`O_(3)=(4)/(48)N, H_(2)O_(2)=(4)/(34)N`

What volume is occupied at N.T.P. by (i) 1.4 g of nitrogen (ii) 6.023 xx 10^21 molecules of oxygen (iii) 0.2 mole of ammonia ?

Avogadro's law states that under similar condition of T and P, equal number of particles. Experiments show that at one atmosphere pressure and at a temperature 273 K (i.e. at STP) one mole of any gas occupies a volume approximately 22.4 litre. Therefore number of moles of any sample of gas can be found by comparing its volume at STP with 22.4. 1 mole of any species contains 6.023xx10^(23) particles which is denoted by symbol N_(A) . Number of atoms present in 1 gm-atom of an element or number of molecules present in 1 gm-molecule of any substance is equal to N_(A) . Hence it is number of particles present in one mole of the substance. The number of gm atoms of oxygen present in 0.2 mole of H_(2)S_(2)O_(8) is.
