Question

What is the molarity of a solution containing 3.5 moles of HCl in 5.0 L of water?

Answer 1

Answer:

0.70 M

Explanation:

• Molarity is the concentration of a given solution in moles per liter.
• Molarity is given in moles per liter of solution.
• It is calculated by dividing the moles of solute by the volume of solution.

In this case;

We are given;

Number of moles of HCl = 3.5 Moles

Volume of solvent, H₂O is 5.0 L

But, $Molarity =\frac{Numberofmoles}{Volume}$

Therefore;

$Molarity=\frac{3.5moles}{5.0L}$

                   = 0.70 M

Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter
