The molar mass of CO2 is 44.01 g/mol. Which is the mass of 3.21*1025 molecules of CO2

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
