Question

What is the molarity of a solution containing 5 moles of HCl in 2.5 L of solution? Be sure to include the formula for calculating molarity and show your work for each step in the calculation.

Answer 1

Answer:

$\boxed{\text{2 mol/L}}$

Step-by-step explanation:

$c = \dfrac{ \text{moles} }{ \text{litres}}\\\\c = \dfrac{n }{V }$

Data:

n = 5 mol

V = 2.5 L

Calculation:

$c = \dfrac{ \text{5 mol} }{\text{2.5 L}} = \text{2 mol/L}$

The molar concentration of the solution is $\boxed{\textbf{2 mol/L}}$.
