What is the numbers of molecules for 65.8g of CO2?

Sagot :

Answer:

8.98*10^23 molecules CO2

Explanation:

The molar mass of CO2 is 44.0 grams/mol. If we convert 65.8 grams of CO2 into moles, 65.8g CO2 / 44.0g CO2 then we get about 1.49 moles of CO2. We know there are 6.02*10^23 molecules in a mole, so we would just multiply 1.49 mol CO2 * 6.02*10^23 = 8.98*10^23
