How do you find the mass of glucose in a solution of 50 ml water and 50 ml 20% glucose solution? The 20% glucose solution is made of four parts water and one part glucose.

Question

bellablain · Answer

Percent by mass	=	mass of solute
mass of solution	X	100%

bellablain · Answer

percent by mass=mass of solute over mass of solution x100%

anonymous · Answer

so m = 50/50 x 1? If the solution was 25 ml of the 20% glucose and 75 ml of water it would be m = 25 / 75 x 1?

aaronq · Answer

you need to know the density of the solution

20% glucose solution implies that there is 20 grams of glucose in every 100 grams of solution, but you dont know how much it weighs.

anonymous · Answer

its the 20% glucose solution but it is diluted by the other grams of water. The reason I'm asking this is because they said they wanted "the percent mass of glucose in the solution."
