Question

A $5.0$M solution of $HCl$ has how many moles of $H^{+}$ ions in $1$ liter of the solution?

• A. $0.50$
• B. $1.0$
• C. $2.0$
• D. $2.5$
• E. $5.0$

Answer 1

The correct option is E $5.0$

Since $Molarity=\frac{No.ofmolesofsolute}{1000mlofsolution}$

Here molarity is given as 5 M

Hence, $5$ moles of $H^{+}$ in $1$ litre
