Get a 100 mL volumetric flask and the distilled water from the stockroom. Transfer 40 mL of the 70% alcohol solution to the volumetric flask and then fill the flask to the 100 mL line with the distilled water. Measure the mass of 10.00 ML. Calculate the density and concentration. Show your calculations below.
Mass of 10.00 ML= 9.5266g
