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

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

Step-by-step explanation:

`c = \frac{ \text{moles} }{ \text{litres}}\\\\c = (n )/(V )`

Data:

n = 5 mol

V = 2.5 L

Calculation:

`c = \frac{ \text{5 mol} }{\text{2.5 L}} = \text{2 mol/L}`

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