20 g of glucose was dissolved in 200g of water to prepare an aqueous solution. calculate the mass percentage of glucose in the solution.
Answers
Mass of solution =200+20=220g
Mass%=(Mass of solute/mass of solution) ×100
Mass%=(20/220)×100
Mass%=100/11
Mass%=9.09%
Answer: The correct answer is 9.09 %
Explanation:
The mass percentage is known as the mass of the total number of atoms present in the element or the solute which is dissolved in the solvent to form the solution which is divided by the mass of the compound which is formed by the joining of two different elements, for example, Ca O that is calcium oxide is the compound where Ca that is calcium and O that is oxygen are the elements or solute and the result whichever comes is multiplied by the 100 to get the percentage. The composition of a solution can be described as a mass percentage indicating the mass of solute present in a given volume of the solution. The amount of solute is expressed in mass or in moles. For a solution, the mass percent is described as grams of solute per gram of solution.
Given is
Mass of solute=20g
Mass of solvent = 200
Mass of solution will be
200 + 20 = 220g
Solution is
Mass% = (Mass of solute/mass of solution) ×100
Mass% = (20/220)×100
Mass% = 100 / 11
Final answer is
Mass% = 9.09%
