Syrup is made of equal parts of water and sucrose. Mass of 1 cup of sucrose is 200.0g and mass of 1 cup water is 220g. what temperature will the syrup boil and freeze?
Solutions
Expert Solution
freezing point of solution =
freezing point of pure solvent(water here i.e 0°C) - dTf .
Boiling point of solution = boiling point of pure solvent (water , 100°C) + dTb .

1)
Syrup used in hummingbird feeders is ofter 25% sucrose
(C12H22O11) by mass. If you wish
prepare 750 grams of this solution what mass of sucrose (g) and
what mass of water (g) would you use?
2)
What is the molality (m) of the solution above? Please give
answer to two (2) decimal places
3)
The density of a 25% sucrose solution is 1.10 g/mL. Please
calculate the Molarity of this solution.

A cup of coffee is made with boiling water at 100 and stands in
a room where the temperature is 25. The change in temperature, H in
degrees , with respect to time t, in minutes, is given by the
following differential equation. (dH)/(dt)=-k(H-25) Solve this
differential equation. If the coffee cools to 90 in 3 minutes, how
long will it take to cool to 60 degrees? Round your answer to the
nearest integer.

Chemistry: Calorimetry and Heats of Reaction
Mass of water in styrofoam cup: 100g
Mass of KCl: 1.650g
Initial Temperature: 20.6degC
Final Temperature: 19.6degC
q=(75g)(1.0 cal/g x degC)(-1degC)= -75cal
qreaction= -qcontents
-75 cal = 75 cal --> 0.075kCal
1.650g KCl = 0.2214 mol KCl
0.075kCal/0.02214mol = 3.39kCal mol KCl
