Question

Calculate mass of 3.24x10^-15 molecules of CO2

Answer 1

Therefore, the mass of 3.24 x 10^-15 molecules of CO2 is approximately 7.304 x 10^-14 grams.

Step-by-step explanation:

To calculate the mass of a certain number of molecules of a substance, you need to know the molar mass of the substance and convert the number of molecules to moles.

The molar mass of CO2 is 44.01 g/mol. To convert the number of CO2 molecules to moles, we can use Avogadro's number which is 6.022 x 10^23.

So, moles of CO2 = (3.24 x 10^-15 ) / (6.022 x 10^23)

mass of CO2 = moles * molar mass = (3.24 x 10^-15 ) / (6.022 x 10^23) * 44.01 g/mol = 7.304 x 10^-14 g

Therefore, the mass of 3.24 x 10^-15 molecules of CO2 is approximately 7.304 x 10^-14 grams.
