Given information
A solution contains of an unknown compound dissolved in of water. (Assume a density of for water.) The freezing point of the solution is . The mass percent composition of the compound is and ; the rest is .
Step-by-step explanation
Step 1.
The mass of water for the given solution is calculated by:
The equation can be further rewritten as,
Putting the values,
To convert mass from into ,
Depression in freezing point of water is calculated by,
Rearranging the equation,
Where,
-
is the depression in freezing point.
-
is the normal freezing point of water.
-
is the freezing point of the solution.
Putting the values,
