Quizplus · Accepted Answer

To determine the number of moles of the solute, we need to use the formula:

moles = (concentration) x (volume in liters)

First, we need to convert the volume of the solution from milliliters to liters:

250 mL = 0.25 L

Now, we can plug in the values:

moles = (3.0 M) x (0.25 L)
moles = 0.75 mol

Therefore, the answer is C) 0.75 mole.
