Question

a solution is prepared by adding 4 gram of substance A to 36 gram of water calculate the mass percent of the solute

Answer 1

Answer:

Mass % of solute in the solution = 10 %

Explanation:

Given :- mass of solute :- 4 gm

             mass of water :- 36 gm

To find :- mass percent of solute .

Solution :-

Step 1) write down the given data from the question :-

Let , mass of solute A ( Wa ) :- 4 gm

       mass of water ( W ) :- 36 gm

Step 2)  Total mass of solution = 4 + 36 = 40 gm

Step 3)  Formula we will use is , mass % of solute = ( mass of solute ) / ( total mass of solution ) * 100 .

mass % of solute = $(4 / 40) *100 = 10$

therefore , mass % of solute = 10 %
