If 155 g of sugar can be dissolve in 100g of water at 20 degree than how much sugar will be dissolved in 300 g of water at same temperature if someone do I will make you

465 grams of sugar.

Explanation:

I'm not sure this is true: is the relationship linear?

If it is then 300 grams of water should be able told 3*155 grams of sugar

3 * 155 = 465  grams of sugar in 300 grams of water.

75 g of water at 20 degrees C would hold dissolved (203.9 g) x (75/100) =152.9 g of sugar.   (300.0 g initially) - (152.9 g remaining in solution) = 147.1 g sugar crystallize out

Explanation:

c)as speed changes, wavelength and frequency change.

everything changes!
