If a 1.45 M solution has 2.43 g HCl dissolved, what is the volume of solution? (Change g HCl into mol using molar mass)
Ulleksa [173]

Answer: The volume of solution is 0.0459 L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of HCl (solute) = \frac{\text {given mass}}{\text {Molar mass}}=\frac{2.43g}{36.5g/mol}=0.0666

Now put all the given values in the formula of molality, we get

1.45M=\frac{0.0666}{V_s}

V_s=\frac{0.0666}{1.45}=0.0459

Therefore, the volume of solution is 0.0459 L

Is this reversible? “ it was silver in color at start but it burned brightly and formed a white powder after heating.”
NARA [144]

Hey there!

This is not reversible.

We know that this is a chemical change because heat is released (it burned brightly) and it formed a new substance (white powder).

Chemical changes are usually not reversible.

Since this is a chemical change, then this is not reversible.

Hope this helps!
