Given:
Molar mass of CO2 = 44.01g/mol
3.21x10^25 molecules of CO2
Required:
Mass of CO2
Solution:
Avogadro’s number states that
for every mole of atom, there are 6.023x10^23 units of atom. The units may be
formula units, atoms. In here, you need to divide 3.21x10^25 molecules of CO2
to 6.023x10^23 molecules per mole.
3.21x10^25 molecules of CO2 / 6.023x10^23
molecules per mole = 53.30 moles CO2
53.30 moles CO2 (44.01g/mol CO2)
= 2346 g of CO2
