Question

how many gram atom and no of atom are there in 224.4g of cu

Answer 1

#No. of gram atoms of Cu = given gm mass of Cu / atomic mass of Cu
➡ = 224. 4 gm / 63 .54 gm
➡ = 3.53 gram atoms of Cu

# Now let's calculate no. of atoms present in
224.4 gm of Cu

No. of atoms present in 224.4 gm of Cu is equals to
➡ = [224.4 / 63.54 ] ✖ 6.022* 10 ^23
➡ = 21.3 * 10^23 .

#Hence answer of given question is that no. gram atoms are 3.53 ND no. of atoms present in 224.4 gm of Cu are 21.3 *10^23 atoms. #

I hope this will help you friend.
