🤓 Based on our data, we think this question is relevant for Professor Halasyamani's class at UH.
We’re being asked to calculate the molarity (M) of an aqueous solution that is 22.3% by mass calcium chloride. Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
We first need to determine the number of moles of calcium chloride (CaCl2). We’re given the mass percent of calcium chloride in the solution water, 22.3%. Recall that mass percent is given by:
Calculate the molarity of an aqueous solution that is 22.3% by mass calcium chloride. You might need to know that the density is 1.20 g/mL.
