Question

5. Calculate the number of molecules present in 22 g of CO2 ?​

Answer 1

Answer:

Mass of CO2=(6)+2(8)=6+16=22

No of molecules=22/22=1

Answer 2

Answer:

molecular mass of co2=44gm

no. of moles(n) =given mass/molecular mass

n=22/44=1/2

1 mole contains 6.022×10^23 molecules

1/2 moles contains (6.022×10^23)/2molecules

=3.011×10^23molecules
