At 70 oC temperature :
the solubility of KCl = 49 g KCl / 100 g water
49 g KCl ----------------> 100 g water
50 g KCl ----------------> 100 g water
so all KCl will dissolve . so this is saturated solution
If you dissolve a bit less than 50 grams of l in 100g of 70 degree...

you weigh out 7.25 grams of NaCl and dissolve this sample in 50 mL of deionized water, and then you put it in an empty volumetric flask weighing 57.221 g. After the whole thing has dissolved, you add water all the way up to the 100.0 mL mark of the volumetric flask (flask and solution together weighs 162.9145 g.) what’s the mass % of NaCl in this solution?
How many grams of ethanol, CH3CH2OH, would you dissolve in water to make 2.75 L of vodka (which is an aqueous solution that is 6.86 M ethanol)? Using the density of ethanol (0.789 g/mL), calculate the volumes of ethanol and water you need to make 2.75 L of vodka. Please show all work. Thank you!
Experiment about viscosity... An amount 50% sugar solution was made using 200ml of water and 100g of sugar.It was mixed until completely dissolved.A metal ball was dropped in the solution and I recorded the time it would take to reach the bottom. I repeated the procedure increasing the percentage of sugar concentration. 70% and 80%. The time for each trial was the same . What did I do wrong?
