24. Calculate the number of
molecules in 2.2 g of CO2 *​

Answer 1

Answer:

The molar mass of CO2 is 44 g/mol. So, there are 6.022 * 10^23 molecules of CO2 in 44g.

Hence, in 1 gram, there will be the same number of molecules of CO2 divided by 44.

Now, in 2.2g of CO2, there will be 6.022 * 10^23 * 2.2 / 44 molecules of CO2, which equals 0.3011 * 10^23 molecules.

Answer 2

The molar mass of CO2 is 44g/mol. So, there are 6.022*10^23 molecules of CO2 in 44g.

Hence, in 1 gram, there will be the same number of molecules of CO2 divided by 44.

Now, in 2.2g. of CO2, there will be 6.022*10^23*2.2/44 molecules of CO2 , which equals 0.3011*10^23 molecules.
