(a) g
(b) mL
(c) L
(d) mols
(e) %

Answer 1

The final unit for the volume of a solution in which the molarity and moles of solute are given is liters (L). Using the formula volume = moles of solute / molarity, the volume can be calculated and expressed in liters.

Step-by-step explanation:

The question provided is asking for the volume of a solution when the molarity (M) of the solution and the amount of solute in moles are given. Molarity is defined as moles of solute per liter of solution, often represented as mol/L or M. Therefore, to find the volume, we will use the formula volume = moles of solute / molarity.

In this case, the student has a solution with a molarity of 2.8 M, and they have 0.70 moles of solute. Using the formula, we calculate the volume as:

Volume = 0.70 mol / 2.8 M = 0.25 L

Thus, the final unit for the volume of the solution in this problem is (c) Liters (L).
