Question

What is the molarity of a solution that contains 5.46 moles in 840 mL?

6.5
0 4.90
O 4586
O 0.0065
0 3.9
0 7.46

Answer 1

6.50M

Step-by-step explanation:

Molarity, M, is an unit of concentration widely used in analytical chemistry. Is defined as the ratio between the moles of solute (In this case, 5.46 moles) and liters of solution. To solve this question we must find the volume of the solution in liters in to find the molarity of the solution, as follows:

Liters solution:

840mL * (1L / 1000mL) = 0.840L

Molarity:

5.46moles / 0.840L

6.50M
