Question :—
1. Calculate the mass percent of salt in salt water if 1 gram of salt is dissolved into 99 grams of water. Show the steps in your calculation.
Answer :—
Mas of common salt (solute)=1 g
Mas of common salt (solute)=1 Mass of water (soluted) =99 g
Mas of common salt (solute)=1 gMass of water (soluted) =99 gmass of solution =1+99 = 100
gconcentration of solution= mass of solution (M mass of solute) ×100 [tex] = > \frac{1}{100} \times 100[/tex]
=> 1% [/tex]Hence, the concentration of the solution is 1%
