Question

calculate the number of moles molecules and total number of atoms present in 1.1 into 10 raise to the power minus 4 kg of CO2 where is c is equals to 12 and is equals to 16​

Answer 1

mass /molar mass = molecules /6.022x10^23

so,

1.1x10^-4 /44 =molecules/6.022x10^23

molecules = (10^-5x 10^23 x 6.022)/4

= 1.5055 x 10^18

and. atoms = 3 x molecules.
