Pyrex and other borosilicate glass expand by 0.0010 % per degree. Calibration of a volumetric flask: An empty 25-mL volumetric flask has a mass of 10.313 g. After addition of water, the mass is 25.225 g. If the lab temperature is 27 o C, please find the real volume of water the flask If 5 844 g of NaCl was dissolved in the flask in the flask. If 5.844 g of NaCl was dissolved in the flask, What is the molarity of NaCl? Home Work of Chapter 2 : 2 7; 2 8; 2 9; 2 21; and 2 24 review Chapter r hursday!!! Preview Chapter 3 for Thursday!!!...
