Question

Calculate the no. Of molecules in 22g of Co2

Answer 1

☑ Check it out

The mass number of CO2 = 2x16 + 12 =44 so one mole of C02 has a mass of 44g. Two moles of CO2 weighs 2 x 44 = 88g. The number of moles in 22g of CO2 = 22/44 = 0.5. One mole always contains the same number of particles which is given by avagadro's number.

Answer 2

Answer:

0.5

Explanation:

Atomic mass of C=12

Atomic mass of O=16

So, Molecular mass of Co2=12+16*2=44

No. of moles in 22 g of Co2 =22/44

=1/2

=0.5

I hope my answer is correct. Have a nice day.☺️☺️
