Answer #1

The complete step wise calculation of  the % by mass of NaCl and CaCl2 in the original mixture is given as below:-

It is given that, mass of the mixture (m) = 12.42 g mixture contains Na ce and Callz. molecular weight af Nace= 58,44 g/mol mso mass of cacla - (12.429 (llig X100 = 0.1119)x100 = 11.19% (%o mass afCacle = 11-19 % So, the % by mass of Nace = 21.25 % a
