molar mass is 249.7 g

Next, the general chemistry student prepares a dilute solution of copper(II) sulfate. The student performs the following steps to prepare a stock solution: 1. The student tares the balance and places a 250.0mL volumetric flask on the balance, which displays a mass of 112.43g. 2. Then, the student adds copper(II) sulfate pentahydrate (refer to the pre-lab and SDS for the molar mass) to the flask until the mass reads 169.05g. 3. Then, the student adds about 100mL of water to dissolve the solid in the flask. Once all the crystals are dissolved, the student uses deionized water to dilute to the 250.0mL mark on the flask. The student measures the mass of the flask and solution as 322.86g. The student labeled this solution as "Stock Solution." Table 1: Preparing the CuSO45H2O solution. Then, the student measured 25.00mL of the "Stock solution" and dispensed the solution into an empty 125.0mL volumetric flask. The student added enough deionized water to the flask until the solution's meniscus reached the mark on the flask. The student labeled this solution "Dilute solution." Use the data to calculate the molarity of copper(II) sulfate in the dilute solution. Report your answer to the appropriate number of significant figures and unit abbreviation (M)
