# Question #4c2a5

You have to consider how many moles of $C {l}^{-}$ ions are released by every mole of the substance
A: 1 mol $C {l}^{-}$ per mol $\to 0.10 \times 1 = 0.10 M$
B: 2 mol $C {l}^{-}$ per mol $\to 0.10 \times 2 = 0.20 M$
C: 3 mol $C {l}^{-}$ per mol $\to 0.10 \times 3 = 0.30 M$
D: 2 mol $C {l}^{-}$ per mol $\to 0.05 \times 2 = 0.10 M$
