- statement and explanation
A gas cylinder contains 12 x 1024 molecules of oxygen gas.
If Avogadro’s number is 6 x 1023; Calculate:
1)The mass of oxygen present in the cylinder.
2) The volume of oxygen at S.T.P. present in the cylinder. [O = 16]
If 150 cc of gas A contains X molecules, how many molecules of gas B will be present in 75 cc of B?. The gases A and B are under the same conditions of temperature and pressure.
