Question

Caluculate the number of moles and number of molecules in 22g of CO2​

Answer 1

Answer:

Given mass if carbon dioxide = 22g

Molar mass of carbon dioxide =

Since,

Atomic mass of C = 12

Atomic mass of O = 16

Molar mass of CO2 = 12 + (16*2)

= 12 + 32

= 44 g/mol.

We know that,

No. Of moles =

Mass given in gram/Molar mass

Therefore,

No. Of moles = 22/44

= 1/2

= 0.5 moles

So, No.Of moles of 22 g of carbon dioxide = 0.5 moles...
