Final answer:
The liquid mixture of 50 mol refers to the molarity (M) of a solution, which is a measure of the concentration of a solute in a solution.
Step-by-step explanation:
The liquid mixture of 50 mol can refer to the molarity (M) of a solution. Molarity is a measure of the concentration of a solute in a solution and is defined as the number of moles of solute per liter of solution. To calculate the molarity, you need to know the number of moles of the solute and the volume of the solution. For example, if you have 50 moles of a substance dissolved in 1 liter of solution, the molarity would be 50 M.
