You have to figure the moles of each salt in the solution:
moles=massSalt/molmassThatSale
then, the moles Cl ion will be
MolesNaCl+2MolesCaCl2 + molesKCl
then molartity Cl ion=totalmolesaboveCl/.1
moles=massSalt/molmassThatSale
then, the moles Cl ion will be
MolesNaCl+2MolesCaCl2 + molesKCl
then molartity Cl ion=totalmolesaboveCl/.1
