3. Calculate the concentration in % (m/m) of the following solution. a. 5.3 g of sugar and 100 mL of water b. Calculate the % of argon gas in a mixture containing 50.0 g of argon gas and 80.0 g of helium gas. C. 0.100 mol of C6H12O6 dissolve in 100 mL of water.
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?
