Question

If 15g of nacl is dissolve in 85g of water than solution is

.

Answer 1

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%
