Mass % of NaCl = mass of NaCl /Mass of solution

To calculate the mass of solution:
Convert the volume of water to ML
1L =1000ML
3.36L=?mL
Volume of water in mL=3360mL

Density of water= mass/volume
0.997 g/mL= mass/ 3360mL
Mass of water = 3349.92g
Mass % of NaCL= (172g / 3349.92 g)x100%
Mass % of NaCL = 5.1%
