Calculate the freezing point of a solution containing 5.0 grams of KCl and 550.0 grams of water. The molal-freezing-point-depression constant () for water is 1.86

The freezing point of solution is -0.454°C

Explanation:

Depression in freezing point is defined as the difference in the freezing point of pure solution and freezing point of solution.

The equation used to calculate depression in freezing point follows:

To calculate the depression in freezing point, we use the equation:

Or,

where,

Freezing point of pure solution = 0°C

i = Vant hoff factor = 2

= molal freezing point elevation constant = 1.86°C/m

= Given mass of solute (KCl) = 5.0 g

= Molar mass of solute (KCl) = 74.55 g/mol

= Mass of solvent (water) = 550.0 g

Putting values in above equation, we get:

Hence, the freezing point of solution is -0.454°C

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
