11.35 g (about one tablespoon) of table sugar (sucrose, C12H22O11) is dissolved in 242.9 mL of water (density 0.997 g/mL). The final volume is 250.0 mL (about one cup). 1.Calculate the molarity of sucrose in this solution. 2.Calculate the molality of sucrose in this solution. 3.Calculate the mass percent of sucrose in this solution.

Expert Solution

1 ) Molarity of sucrose = Wt/Mwt * 1000/v

= 11.35/342 * 1000/250

= 0.133M

2) Molality of sucrose = Wt/Mwt * 1000/w

= 11.35/342 * 1000/242

= 0.137m

3) mass percent = gr solute / gr solution * 100

= 4.54

A sugar cube (sucrose) weighs about 3 g. A 20 oz. (591 mL) container of Gatorade (or Powerade) contains 35 g of sucrose (table sugar). 1.0 oz. = 28.35 g. Sucrose is a dissaccharide consisting of glucose and fructose (a 1:1 ratio). Gram molecular weight (GMW) of sucrose = 342.2 g/mole. When ingested, sucrose is rapidly broken down into glucose and fructose by enzymes in your body. In humans, normal blood glucose levels are maintained at about 0.005 moles/L (which...
