0.2 moles of HCl and 0.1 moles of calcium chloride were dissolved in water to have the molarity of Cl- ions is

Question

0.2 moles of HCl and 0.1 moles of calcium chloride were dissolved in water to have the molarity of Cl- ions is (A) 0 04 M (B) 0.8 M (C) 0.4 M (D) 0 08 M

Tardigrade Admin · Accepted Answer

0.2 moles of HCl gives Cl- ions = 0.2 moles 0.1 moles of CaCl2 gives Cl- ions = 0.2 moles. Total moles of Cl- ions in 500 mL = 0.4 Molarity of Cl- ions = 0.8 M.

Q. 0.2 moles of HCl and 0.1 moles of calcium chloride were dissolved in water to have the molarity of $C l^{-}$ ions is

0 04 M

0.8 M

0.4 M

0 08 M

0.2 moles of HCl gives $C l^{-}$ ions = 0.2 moles 0.1 moles of $C a C l_{2}$ gives $C l^{-}$ ions = 0.2 moles. Total moles of $C l^{-}$ ions in 500 mL = 0.4 Molarity of $C l^{-}$ ions = 0.8 M.
