Question

OCEDURE Note: The accuracy for the calculated mass percent when compared to the actual value will be worth 10% of this lab report. 1. Determine how much Na,SO, is required to prepare a 100 ml solution of 0.1 M NasO Report the mass calculated on the report form and include the calculation. . Weight out the required Na,SO, to prepare the solution and record the mass on the report form, Prepare the solution using the 100.00 mL volumetric flask (5 significant figures) and calculate the actual molar concentration. Include the calculation for the determination of the actual concentration on the report form

Explanation / Answer

Molar mass of Na2SO4 = 142.04

100 ml of 0.1 M Na2SO4 = 100 x 0.1 x 142.04 / 1000 = 1.4204 gram of Na2SO4 is need
