Answer
a. 1.00 M
b. 2.0 M
c. 0.187 M
d. 0.0188 M
Work Step by Step
a. $\frac{0.100 \text{ mol}}{0.1000 \text{ L}}=1$M
b. $\frac{2.5\text{ mol}}{1.25\text{ L}}=2$M
c. $5.00 \text{ grams}∗\frac{1\text{ mol}}{53.491\text{ grams}}=0.0935 \text{ moles}$
$\frac{0.0935 \text{ mols}}{0.500 \text{ L}}=0.187 \text{ M}$
d. ${1.00\text{ grams}}∗\frac{1\text{ mol}}{212.27\text{ grams}}=0.00471 \text{ mol}$
$\frac{0.00471 \text{ mol}}{0.2500\text{ L}}=0.0188$ M
