Question

When 56 grams of `NaCl` are dissolved in enough water to create a 125 gram solution, what is the solution's concentration, expressed in percent by mass?

Answer 1

`"Mass %"` `=` `"Mass of solute"/"Mass of solution"xx100%`

Explanation:

And thus `"Mass %, sodium chloride solution"` `=` `(56*g)/(125*g)xx100%` `=` `??%`
