Question

calculate the mass of 1.0505x1023
molecules of carbon di oxide (co2).​

Answer 1

Explanation:

Gram Molecular Mass of CO₂ = (12 + 32) = 44 gm

∴ Mass of 6.023 × 10²³ molecules of CO₂ = 44 gm

[Mass of Avagadro number of molecules = Gram molecular mass of the compound]

∴Mass of 1.0505 × 10²³ molecules of CO₂ =

$\frac{44*1.0505*10^{23}}{6.023*10^{23}}\:gm\\\\= 7.674\:gm$

∴Required Mass of CO₂ = 7.67 gm
