The basic equation for diluting solutions is:

(M1)(V1) = (M2)(V2)

M1 and V1 belong with the stock solution, the stronger one.

The mL has to be turned into liters, so convert first. 175 mL = .175 L

So, 1.6 M represents M1 and .175 L represents V1. 1.0 is V2 because it's asking for the new concentration, which is M2. Therefore, M2 is the variable you're looking for.

Plugging it in:

(1.6M)(.175) = (M2)(1)

Simplify and Solve:

.28 = M2
