Answer:

9.38 moles NaNO₃

Step-by-step explanation:

Given the measurements provided, the best way to find moles is by using the molarity formula. The molarity formula is:

Molar concentration (M) = moles / volume (L)

Therefore, plug the provided values into the formula, then isolate to find moles.

Molar concentration (M) = moles / volume (L)

0.750 M = moles / 12.5 L

(0.750 M) x (12.5 L) = moles

9.38 = moles
