Question

A solution is prepared by dissolving a certain amount of solute in 500g of water. The percentage by mass of a solution is 2.38%. Calculate the mass of solute. ​

Answer 1

Answer:

Weight percentage=[  

Weight of solute+ weight of solvent

Weight of solute

​  

]×100  

Let the weight of the solute be 'x'.

2.38=  

x+500

x×100

​  

 

⟹2.38x+1190=100x

⟹1190=97.62x

⟹x=  

97.62

1190

​  

=12.190g

∴ Mass of solute =12.19 grams
