Material: turkey baster
a tall glass ( about 6 in high, 2.5 in wide)
a smaller glass
a can of Mountain Dew or equivalent in color
strawberry Cool Aid or powder equivalent in color
Experiment:
Fill a third of the tall glass with Mountain Dew . Prepare in the small
glass a concentrated
solution of Cool Aid by dissolving two large tablespoons of powder in water(or three little packages). Stir.
Remove the rubber top of the turkey baster and use the wide plastic pipette
as a funnel.
Dip this funnel in the Mountain Dew( large glass) in such a way that the
tip of the funnel
touches the bottom of the glass.
Pour very,very slowly some of the Cool Aid in the pipette/funnel and observe
it push the
Mountain Dew up in the glass. Very,very
slowly remove the pipette and you can enjoy that special drink, sample
each
layer with a straw...and fill in the report.
PLEASE PRINT THIS REPORT AND COMPLETE. Name: _____________________
Calculations: use the following conversions
: 1 inch = 2.54 cm
1 cm 3 = 1 ml
1 oz = 28.349 g
1 liter = 0.264 gallon
1 mole of sugar = 342 g
1. calculate the volume of the glass in in 3 , cm 3 and ml ( use the glass above)
ans: _______ in 3
ans:________cm3
ans:________ml
2. compare the density of the Cool Aid to the density of the Mountain Dew:
Higher/Lower?
Explain.
3. determine the density of the Mountain Dew knowing that 355ml weighs
380 g.
Express your answer in g/ml and oz/gallon.
ans: ___________ g/ml
ans: ___________oz / gallon
4. compare the density of Moutain Dew to the density of water; Higher/
Lower?
Explain.
5. In a can of Mountain Dew there is 46 g of sugar ( sucrose) :calculate
the number of mole.
ans: __________mol
