how many moles of C02 are present in 51.2 g of it? (atomic mass of carbon = c is 12u and o is 16u)

No. of moles of CO2 = given wt. / Molecular wt.

Molecular wt. of CO2 = 12 + 16+16 = 44 g

Putting the value in formula we get No. of moles of CO2 = 51.2/44 = 1.16 moles of CO2

1 mole of CO2 = 6.022 x 1023 atoms = 44g.

44g of CO2 = 1 mole

hence, 1 gm of CO2 = 1/44 moles

So, 51.2g of CO2 = 1/44 x 51.2

=1.16 moles.
