Question

Calculate the molarity of the following solutions:

0.150 mol of Na₂S in 1.85 L of solution

Answer 1

To calculate the molarity of the given solution, divide the number of moles of Na₂S by the volume of the solution in liters. The molarity of the solution is 0.0811 M.

Step-by-step explanation:

To calculate the molarity of a solution, you need to divide the number of moles of solute by the volume of the solution in liters. In this case, you have 0.150 mol of Na₂S and a volume of 1.85 L of solution. Therefore, the molarity would be:

Molarity = (0.150 mol) / (1.85 L) = 0.0811 M

So, the molarity of the solution is 0.0811 M.
