Answer: 
Explanation:
Depression in freezing point is:
where,
= freezing point of solution = ?
= freezing point of solvent (cyclohexane) = 
= freezing point constant of solvent (cyclohexane) = 
m = molality
i = Van't Hoff factor = 1 (for non-electrolyte)
= mass of solute (biphenyl) = 0.771 g
= mass of solvent (cyclohexane) = 25.0 g
= molar mass of solute (biphenyl) =
Now put all the given values in the above formula, we get:
Therefore, the freezing point of a solution made by dissolving 0.771 g of biphenyl in 25.0 g of cyclohexane is
Answer:
0.01790670606142 we assume you converting between moles fe and gram. you can reveiw more details on each measurement unit: molecular weight of fe or grams the sI base unit for amount of substance is the mole.1 mole is equal to 1 moles fe,or 55.845 grams
Answer: n=2,l=1,ml=1 n=3,l=2,ml=0 n=3,l=3,ml=2 n=4,l=2,ml=0.
Explanation:

In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.
So what am I suppose to answer here?
