Question

What is the mass of a molecule of CO2 in grams? (Molar mass of CO2 = 44 g mol-1 )​

Answer 1

Answer:

The mass of a molecule of CO2 in grams is 7.3065x10^-23 grams.

Explanation:

1 mol of CO2 weighs 44g

Applying for Avogadro’s number, 1 mol contains 6.022x10^23 molecules.

So 1 molecule weighs 44/(6.022x10^23) = 7.3065x10^-23 grams.

Answer 2

The molar mass of CO2 is 44 g that means 1 mole of CO2 has a mass of 44 g.

1 mole has 6.6 × 10²³ molecules of CO2

∴ MASS OF 6.6  × 10²³  molecule  =  44 g

   MASS OF 1 molecule     =     44 /  6.6  × 10²³

                                            =  2.9 × 10⁻²³ g
