a) Calculate the number of molecules present in the sample ?
b) Calculate the number of moles present in the sample ?
c) What is the GMM ?
d) Calculate the volume of the gas .​

Answer 1

Answer:

Gram molecular weight of CO2 = 12+2 × 16 = 44g.

Now, 44g of CO2 contains 6.023×1023 molecules.

∴ 11g of CO2 contains  = 446.023×1023×11 = 1.51×1023 molecules.
