Question

calculate the number of moles molecules and the number of atoms in 1.1 into 19
$10 { - }^{3$
kg of co2​

Answer 1

given mass =1.1kg= 1100g

No. Of moles= 1100/44(mw of co2)= 25.

No of. Molecules = no. Of moles. Na

25. 6 10^23

No of atoms= no of molecules. No of atom in 1 molecule i.e. CO2 has 3atoms so total no of atoms = 25* 3*Na = 75Na

Hope it helps
