QUESTION:
If 3.5 L of a 4.8 M SrCl2 solution is diluted to 45 L, what is the molarity of the diluted solution?
ANSWER:Solution: Here, we are going to calculate the molarity of the given solution. Also, we are going to calculate the number of moles of KBr present in 150 mL of a 0.112 M solution and volume in millilitres of a 6.1 M HCl solution needed to obtain 0.150 mol of HCl. Step1: Molarity is defined as the number of moles of the solute(Here Na CrO is th2solu4) in 1 litre of the solution. Mathematically, Number of moles of solute Molarity(M) = -------------------------------------- ------(1) Volume of solution in litres In order to calculate molarity of Na CrO2solu4on, we have to first calculate the number of moles of Na C2 di4olved in the solution. Number of moles can be calculated by the fo
