Answer
a.
$$1.3 \space mol \space KCl$$
b.
$$1.5 \space mol \space KCl$$
c.
$$ 0.211 \space mol \space KCl$$
Work Step by Step
1. Knowing that "M" represents "mol/L":
a.
$$0.556 \space L \times \frac{2.3 \space mol \space KCl}{1 \space L} = 1.3 \space mol \space KCl$$
b.
$$1.8 \space L \times \frac{0.85 \space mol \space KCl}{1 \space L} = 1.5 \space mol \space KCl$$
c.
$$114 \space mL \times \frac{1 \space L}{1000 \space mL} \times \frac{1.85 \space mol \space KCl}{1 \space L} = 0.211 \space mol \space KCl$$
