In this question, we have to find the molar concentration of the acid, and the question already provides us with the formula and each required data:

MaVa = MbVb

We have:

Ma = ?

Va = 100 mL

Mb = 1.0 M

Vb = 25 mL

Now we add these values into the formula:

Ma * 100 = 1 * 25

100Ma = 25

Ma = 25/100

Ma = 0.25 M
