Question

find the number of molecules present in 2.5 moles of water

Answer 1

To get the number of molecules in 2.5 moles of CO2, you have to multiply the number of moles of CO2 by the Avogadro’ constant (6.022 X 10^23). Therefore, the number of molecules in 2.5 moles of CO2 would be:

(6.022 X 10^23 X 2.5)=1.5055 X 10^24 molecules of carbon (IV) oxide.

However, if the number of moles is not provided, then you have to calculate the number of moles first. If you are wondering how to do that, do not hesitate to check it here

The article provides step by step how to calculate the number of molecules of a chemical compound when the number of moles is not provided.

Answer 2

HEY FRND HERE IS UR ANS.....

We know 1 mol = 6.022 × 10^23

so., 2.5 mole contain = 6.022 × 10^23/ 1 mol ×2.5 = 1.5 × 10^24
