Q. What is the total number of moles of $H_{2}{SO}_{4}$ needed to prepare 5.0 L of a 2.0 M solution of $H_{2}{SO}_{4}$ ?
A) 2.5
B) 5.0
C) 10
D) 20
Explanation
(c)
Number of moles = Molarity $\times \$Volume (in L)
$\Longrightarrow$ Number of moles of $H_{2}\ SO_{4}\ = \ 2.0\ M \times \ 5.0\ L$
= 10 moles
