A 1.0 mL aliquot (sample) is taken from a 1.0L solution. Which of the following is/are true when comparing the 1.0 mL solution to the 1.0L solution? Choose all that are true. a. The molarity of the 1.0 mL solution is less than the molarity of the 1.0L solutionb. The molarity of each is the samec. The number of moles of solute in each solution is the samed. The number of moles of solute in the 1.0mL solution is less than the number of moles of solute in the 1.0 L solution

b. The molarity of each is the same

d. The number of moles of solute in the 1.0mL solution is less than the number of moles of solute in the 1.0 L solution

Explanation:

Molarity is an unit of concentration defined as the ratio between moles of solute and liters of solution. Also, when you take an aliquot of an homogeneous solution, molarity of solution and aliquot is the same. Knowing this:

a. The molarity of the 1.0 mL solution is less than the molarity of the 1.0L solution. FALSE. Assuming solution is homogeneous, molarity of both solution and aliquot is the same

b. The molarity of each is the same. TRUE.

c. The number of moles of solute in each solution is the same. FALSE. As molarity is the same but volume of solution is higher than volume of aliquot, there are more moles in solution than in aliquot.

d. The number of moles of solute in the 1.0mL solution is less than the number of moles of solute in the 1.0 L solution. TRUE.

I hope it helps!
