Question

Calculate the percent by mass of a solution made from 14 g nacl (the solute) and 61 g water

Answer 1

The percent by mass of  an answer  made from 14 g NaCl (the solute) and 61 g water is 18.66%

14 g + 61 g =75.0 g - mass of the solution

mass % = (mass solute/ mass solution)*100% = (14/75.0)*100% =

= 0.186*100% =18.66%.

What is the percent by mass?

Mass percent is another method of expressing the composition of the solution mixture. It describes the amount of solute (grams) present in 100 gm of the solution.
