Convert 12.3 grams of CO2 to moles.

Answer 1

To convert grams of CO2 to moles, we need to divide the given mass by the molar mass of CO2.

The molar mass of CO2 is 44.01 g/mol (12.01 g/mol for carbon + 2(16.00 g/mol) for oxygen).

Dividing 12.3 g by 44.01 g/mol gives:

12.3 g / 44.01 g/mol = 0.279 moles

Therefore, 12.3 grams of CO2 is equivalent to 0.279 moles.
