Question

Calculate the mass of glucose required to make a solution of volume 250ml and the concentration of 40%

​

Answer 1

please mark me as brainlist

Mass percent = 40 Hence 40 % = X/ 250 ? X= 100g Hence amount of glucose needed to make 250g of 40 % solution of is 100 g As we know Mass of solution = mass of solute + mass of solvent Therefore Mass of Solvent = 250g – 100g Hence the mass of solvent(water)= 150g

Answer 2

Answer:

We know that,

Mass percent = mass of solute / mass of solution

Here mass of solution = 250g

Mass of solute = X

Mass percent = 40

Hence 40% = X/250

Therefore X = 100g

Hence amount of solute needed to make 250g of 40% solution is 100g

As we know mass of solution = mass of solute + mass of solvent,

Therefore mass of solute = 250g – 100g

Hence the mass of solute = 150g
