Question 1137381: There are 100g of sugar dissolved in 1.5l of water. How much sugar is present if you take 0.5qt of the liquid from the solution?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! you have 100 grams of sugar dissolved in 1.5 liters of water.
you want to remove 1 quart of the solution.
you have 100 grams of sugar dissolved in 1.5 liters of water.
the ratio of grams of sugar to liters of water is 100 / 1.5.
1 quart is equal to 0.946353 liters.
1/2 of a quart is therefore equal to 1/2 * .946353 liters which is equal to .4731765 liters.
when you remove 1/2 of a quart of liquid, you are also removing 100 / 1.5 * .4731765 = 31.5451 grams of sugar.
this assumes the ratio of sugar to liquid remains the same.
the amount of liquid that is left is 1.5 - .4731765 = 1.0268235 liters.
the amount of sugar that is left is 100 / 1.5 * 1.0268235 = 68.4549 grams of sugar.
add up the sugar that is removed and the sugar that is left and you get 31.5451 + 68.4549 = 100 grams of sugar.
add up the liquid that is removed and the liquid that is left and you get .4731765 + 1.0268235 = 1.5 liters of water.
the assumption is that, when you remove the water, you are also removing the sugar that is dissolved in the water.
the question is: How much sugar is present if you take 0.5qt of the liquid from the solution?
if you are asking how much sugar is present in the half a quart that is removed, then the answer is 31.5451 grams.
if you are asking how much sugar is left in the solution after you have removed half a qoart, then the answer is 68.4549 grams.
hopefully, i understood your problem correctly.
let me know if there's another interpretation that i might have missed.
