Question

4. Determine the sugar concentration for Coke & Gatorade by using your calibration graph. Indicate on the calibration graph how you determine the concentrations of each solution.

Information recorded in the lab experiment:

Part C: Specific gravity of sugar solutions:

Standard Sugar Solutions/ Mass of Sugar/ Voume of Solution/ Specific Gravity

#1 / 18.00g / 500.0mL / 1.014

#2 / 36.00g / 500.0mL / 1.028

#3 / 53.00g / 500.0mL / 1.042

Part B: Specific gravity of soft/sports drinks:

Solution / Specific Gravity

Coke / 1.049

Gatorade / 1.024

Explanation / Answer

For Coke:

Y2-Y1 / (X2-X1 ) = (36-53) / (1.028-1.042) = 1214.27 g/spg

y3-y2 = m(x3-xw)

y3 - 53= 1214.27(1.049 - 1.042)

y = 61.498 grams of sugar per 500 ml

For gatorade

y4 - 53= 1214.27(1.024 - 1.042)

y4 = 1214(-0.018) + 53 = 31.14

y = 31.14 g of sugar in 500 ml in Gatorade
