Calculate the Molar Mass

What is the molar mass of CO2?

Choose the correct answer:

a) 44.0 g/mol

b) 32.0 g/mol

c) 28.0 g/mol

Answer:

The correct answer is: a) 44.0 g/mol

To calculate the molar mass of CO2, we add the atomic masses of the elements in the compound. In this case, Carbon (C) has a molar mass of 12.01 g/mol and Oxygen (O) has a molar mass of 16.00 g/mol. Therefore, the molar mass of CO2 is:

Molar mass of CO2 = 12.01 + 16.00 + 16.00 = 44.01 g/mol

So, the molar mass of CO2 is 44.01 grams per mole.

Knowing the molar mass of CO2 is essential for various calculations in chemistry, such as determining the mass of a certain number of moles of CO2 in a given sample.
