Question

HELP PLZ!! When you have a 5.10 M HCl solution, what volume is needed if using 231 g of HCl?

Answer 1

The answer for the following problem is mentioned below.

• Therefore the volume of the HCl solution is 1.24 L

Explanation:

Given:

molarity of the solution (m) = 5.10 M

mass of  solution (m) = 231 grams

Gram molecular mass of hydrogen chloride = 36.5 u

To find:

volume of the solution

We know;

m = $\frac{n}{V}$

Where;

m represents the molarity of the solution

n represents the no of moles of the solution

V represents the volume of the solution

n = $\frac{m}{M}$

where;

n represents the no of moles of the gas

m represents the mass of the solution

M represents the Gram molecular mass of the solution

Therefore;

 n = $\frac{231}{36.5}$

 n = 6.3 moles

So;

 5.10 = $\frac{6.3}{V}$

 V = 1.24 L

Therefore the volume of the solution is 1.24 L
