Question

Number of atoms in 11gram of co2

Answer 1

Answer:

Molar mass of CO2 = Molar mass of C + 2 × Molar mass of O

=12+2×16

=12+32

=44 g/mol.

So, 1 mole of CO2 is 44 gm.

To find: Number of moles in 11 g of CO2.

44gm of CO2 = 1 mole

1 gm of CO2 =1/44 mole

11 gm of CO2 =1/44×11

= 11/44 mole

=0.25 mole.

Answer 2

Heya Mate........

Calculate the number of molecules in 11 g of CO2.

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

Hope this will help you....
