Answer:
7.38654 in 54 grams
Explanation:
To get moles, you divide grams of a substance by molecular weight. The molecular weight of CO2 is 44 g/mol. 54g divided by 44/mol is 1.227moles.
You then need to multiply moles by Avogadro’s constant (6.022x10^23). That gives you 7.38654x10^23 molecules in 54 grams of CO2.
The number of molecules in 54 grams of CO2 is 7.39 × 10²³ molecules.
• To find the number of molecules, first there is a need to find the number of moles in a substance.
• Moles are determined by using the formula, mass of substances/molecular weight of the substance.
• The molecular weight of CO2 is 44 gram per mole.
• So, the number of moles will be,
Number of moles = 54 g/44 g/mol = 1.227 moles
Now to determine the molecules, there is a need to multiply the moles with the Avogadro's constant, that is, 6.022 × 10²³. This comes out to be as,
= 1.227 moles × 6.022 × 10²³
= 7.39 × 10²³ molecules
Thus, the number of molecules in 54 grams of CO2 is 7.39 × 10²³ molecules.
