63.9 grams of carbon dioxide=____ molecules of carbon dioxide​

Sagot :

Solution:

Step 1: Calculate the molar mass of CO₂.

molar mass = (12.01 g/mol × 1) + (16.00 g/mol × 2)

molar mass = 44.01 g/mol

Step 2: Calculate the number of molecules of CO₂.

[tex]\text{number of CO₂ molecules = 63.9 g CO₂} × \frac{\text{1 mol CO₂}}{\text{44.01 g CO₂}} × \frac{\text{6.022 × 10²³ CO₂ molecules}}{\text{1 mol CO₂}}[/tex]

[tex]\boxed{\text{number of CO₂ molecules = 8.74 × 10²³ molecules}}[/tex]
