Determine the moles of atoms for each of...

Determine the moles of atoms for each of the following elements. (a) 36g of C,
(c) 6.4 g of O

Text Solution

Verified by Experts

Solution `n=(m)/(M),m=` mass in g given M=g atomic mass in g `mol^(-1)`, n=number of moles
(a) `m=36g, M=12" g "mol^(-1)" "thereforen=(36g)/(12" g "mol^(-1))=3` mole
(b) `m=6.4g,M=16" g "mol^(-1),n=(6.4g)/(16" g "mol^(-1))=0.4` mole
