How many atoms are in 1.75 mol CHCL3?

i did

1.75 mol CHCL3 ( 6.022 * 10 ^ 23 atoms / 1 mol)

the mols cancel out

then do i multiply 1.75 by 6.022 * 10 ^ 23 ?

i got

1.05 * 10 ^ 23 atoms CHCL3

  • Ok well first off since it is asking for ATOMS that means the atoms within each molecule, so in a molecule of CHCl3 you have 1 carbon atom, 1 hydrogen atom and 3 chlorine atoms, so 5 total atoms per molecule. Now you have 1.75 moles of CHCl3 and a mole is 6.022 * 10^23 molecules so you multiply avadagro's number by the number of moles 1.75*(6.022*10^23)= 1.05385*10^24 molecules, now within each molecule you have a total of 5 atoms, so you would multiply the number of moluecules by the number of atoms per molecule so 1.05385*10^24 * 5= 5.26925*10^24

  • whaattaaa cheater.!

    pffttt. i dont cheat 😉

    and

    yes you multiply it. 🙂
