A student is provided with 500 mL of 600 ppm solution of sucrose. What volume of the
luton a milliers contains 0.15 sucrose?​

Answer 1

Explanation:

Does this mean that I just have to use 600 ppm as the concentration and the 0.15 as the weight? Like this:

600 ppmxx=0.15gx⋅106=0.15600⋅106=250 mL

And when can 500 mL be used?

Assuming it's 0.15gm of fructose,

ppm=Weightofsolute(ingm)Weightofsolution(ingm)106

Since density of water is 1gm/ml, 500ml of water would weigh 500gm

∴600=Wb500106

∴Wb=0.3gm

Thus, 500ml of water contains 0.3gm of fructose. You can find out what volume will contain 0.15gm of it.
