Q. Which of the following solutions contains same molar concentration?

$166 g$ . KI/L solution

$33.0 g (N H_{4})_{2} S O_{4}$ in $200 m L$ solution

$25.0 g C u S O_{4} \cdot 5 H_{2} O$ in $100 m L$ solution

$27.0 m g A l^{3 +}$ per $m L$ solution

a. $M = \frac{166 \times 1000}{166 \times 1000} = 1.0 M$
b. $M = \frac{33 \times 1000}{132 \times 200} = 1.25 M$
c. $M = \frac{25 \times 1000}{250 \times 100} = 1.0 M$
d. $M = \frac{27 \times 1 0 ^{- 3} \times 1000}{27 \times 1} = 1.0 M$
