Question

If 32.3 grams of KCl are dissolved in 192 grams of water, what is the concentration of the solution in percent by mass?

Answer 1

the concentration is 0.168 g/ml

Answer 2

The concentration of the solution in percent by mass is 14.3%

Step-by-step explanation:

Given:

Mass of KCl (solute) = 32.3 g

Mass of water (solvent) = 192 g

To determine:

Concentration of solution in % mass i,e. %(w/w)

Formula:

%w/w
`= (Mass\ of\ solute)/(Total\ mass\ of\ solution ) *100\\`

Total mass of solution = solute + solvent = 32.3 + 192 = 224.3 g

%w/w =
`(32)/(224.3) *100 = 14.3%`
