Video transcript

Hi everyone here we have a question asking us to identify the number of moles of solute in a solution of 0.13 morality calcium hydroxide weighing 563 g. Since the concentration is very low, we can assume that the mass of the solution is approximately the same as the mass of the solvent. So we have 0. moles of calcium hydroxide over one kg of water Times grams of water times one kg, Divided by 10 to the 3rd g Equals 0. moles of calcium hydroxide. And that is our final answer. Thank you for watching. Bye.
