Question

The actual mass of a molecule of carbon dioxide is ?
​

Answer 1

Answer:

44.01 g/mol (molar mass)

Explanation:

Answer 2

Answer:

7.3065 × 10^23gm

Explanation:

Number of molecules =   Number of moles × Avogadro Number

Number moles = Numberof molecules /Avogadro number

Number of moles = 1/6.022 × 10^23. [Avogadro number = 6.022 × 10^23]

Number of moles = mass of compound /molecular weight of the compound

Mass of compound -

Mass = Number of moles *molecular weight of CO2

Molecular weight of CO2

= (1 × 12+2 × 16). ( Since, the atomic mass of carbon and oxygen are 12 and 16 respectively

= 12+32=44

Mass = 1/6.022 × 10^23 × 44

Mass =7.3065 × 10^23gm

Therefore, the actual mass of a molecule of carbon dioxide is 7.3065 × 10^23gm.
