# Find the concentration of the saline solution in terms of % by mass using your exact mass of NaCl, the – Question

**Question:**

Find the concentration of the saline solution in terms of % by mass using your exact mass of NaCl, the volume of water (80.0 mL), and density of water being 0.9981 gmL. Show the calculation in detail with the corresponding units of measurement and the appropriate sig. figs. The mass of NaCl used was 17.518 g.

2) Use the information to calculate the experimental value for the concentration (% by mass) of your saline solution based on your experimental value for density obtained with the volumetric pipette. You must show ALL the work and the calculation leading to the result in detail for full credit. The graph equation given is y=(0.0076x) + (0.9935) where y= density, x= Concentration and the density of solution using one experimental value for volumetric pipette;1.08
