d) 22 .0 g of mass.
Explanation:
1 mol of CO₂ has 6.023 *10 ²³ no of molecule or avogadro no of molecule
no of moles in 3.011* 10 ²³ no of molecule:
= 3.011* 10 ²³ / 6.023 *10 ²³
= 0.5 mole
1 mol of CO₂ = (12 +16+16 ) = 44 g of weight
as molecular weight of CO₂ is also 44 g/mol
0.5 mol will have = 44*.5
= 22 .0 g of mass.
