Explanation:

mass\% =\frac{mass\: of\: solute \times 100}{mass \: of\: solute+mass \: of \: solution}

 =  \frac{5 \times 100}{5 + 15} = 25\%

Therefore , the percentage of Nacl is 25 %.

I hope it helps you. If you have any doubts, then don't hesitate to ask.

Given: A solution is prepared by adding 5g of NaCl salt in 15g of water.

To find: We have to find the mass percentage of NaCl.

Solution:

The mass percentage of NaCl can be determined as follows-

In the solution, NaCl is the solute and water is the solvent.

The total mass of the solution is 5+15=20 grams.

Thus the mass percentage of NaCl is given as-

mass of the solute/total mass of the solution ×100

 \frac{5}{20}  \times 100 \\  = 25\%

The mass percentage of NaCl is 25%.
