Answer:
if 1mole of the compound having 6.022×1023 molecules have mass equal to 44g, then one molecule of carbon-dioxide will have mass=446.022×1023=7.306×10−23g

Answer:
Molar mass of CO2 = (12+2×16) g/mol = 44 g/mol.
1 mole of any substance contains 6.022 × 10^23 (Avogadro number) fundamental units.
1 mole CO2 contains 6.022×10^23 molecules of CO2.
So, mass of 6.022 × 10^23 molecules = 44 g.
Mass of one molecule of CO2 = 44/(6.022×10^23) g = 7.3 × 10^-23 g.
Hope, this helps.
