Calculate the new freezing point for benzene

Reference no: EM13175992

1) Calculate the new freezing point for a 0.61 m solution of CCl4 in benzene.

2) Calculate the increase in the boiling point, Î"T, for a 1.94 m solution of sucrose (dissolves as a molecule) in water

3) Which 0.06 m aqueous solution should have the greatest increase in boiling point?

a. Sugar solution
b. KBr solution
c. MgI2 solution
d. (NH4)2SO4 solution
e. AlCl3 solutio

4) What is the correct procedure for mixing an acid and water and why?

Choose one answer.

a. Order does not matter because you end up with the same final concentration.

b. Water is added to acid to avoid splattering (because water is safer this works better).

c. Acid is added to water to avoid splattering (because it is more dense than water it sinks and disperses better thus spreading the generated heat over a larger volume--no hot spots where boiling would occur).
