Question

Number of carbon atoms present in 22 gram of co2 is

Answer 1

Answer:

1/2 mole of C is present in 22g CO₂ (i.e, 3.011 x 10²⁴ atoms)

Explanation:

Moles of CO₂ = given mass/ molar mass

                       =22/(12+16*2)  

                      =22/44

                      =1/2

In 1 mole CO₂

      moles of C= 1

So by unitary method,

In 1/2 moles CO₂ ,

moles of C =1/2     {i.e., (1/2)*6.022x 10²⁴ = 3.011x 10²⁴ atoms}
