The question in the lab is asking what percentage by mass is the calcium, chloride and water in the orginal solution for each trial. In this lab we performed two trials, in each, we added 50 mL water to 2.0 g of CaCl2. I am confused as to how to find out the percentage composition because i'm not sure if the 50mL water.
