Question

what is mass of water in 15%NaCl solution by mass

Answer 1

Answer:

Note that for D.I. water, the mass of NaCl is zero, so the mass% NaCl is zero. Using a spreadsheet, plot the densities on the yaxis and the mass percent on the x axis.

Answer 2

Mass of NaCl, WA= 15g

Mass of water, WB= 285g

Mass percentage of NaCl = WA × 100 / WA+WB

= 15 ×100 / 15+285

= 1500 / 300

= 5%

Mass percentage of water = WA×100 / WA+WB

= 285×100 / 15+285

= 28500 / 300

= 95%
