Question

A solution is prepared by dissolving 10 g of sodium chloride in 40 g of water. What is the mass by mass percentage of this solution?​

Answer 1

Answer:

Mass of NaCl dissolved = 60 g

Mass of water taken = 400 g

Total Mass of solution =400+60=460 g

Mass / Mass % of NaCl in solution =  

Mass of solution

Mass of NaCl×100

​

 

                                                        =  

460

60×100

​

=13.04%
