Answer : The boiling point of water increases, 
Solution : Given,
Moles of solute (sugar) = 4 moles
Mass of solvent (water) = 1 Kg
i = 1 for sugar
Formula used :
Where,
= elevation in boiling point
= elevation constant
m = molality
= moles of solute (sugar)
= mass of solvent (water)
i = van't Hoff factor
Now put all the given values in this formula, we get the elevation in boiling point of water.
Therefore, the elevation in boiling point of water is
Molecules are the smallest living thing.
Atoms are the smallest thing.
Hope this helps!!:)
Answer:
%age Yield = 66.05 %
Explanation:
In order to check the efficiency of a reaction the %age is calculated so that it can be concluded that either the conditions provided for certain reactions are favourable or not because at large scales reactions with greater %age yields are favoured as it results in high product quantity and hence, greater economical advantages.
The percent yield is given as;
%age Yield = Actual Yield / Theoretical Yield × 100
Putting values,
%age Yield = 253 g / 383 g × 100
%age Yield = 66.05 %
Hence, for the given reaction the success of the reaction is only 65% hence, steps can be made to improve this yield by modifying the reaction conditions.
First, heat the solute to a high temperature, but not boiling. Next, dissolve the solute into the heated solution until the solute will no longer dissolve. Once that happens, take the heated solution off the heat and allow it to cool. Once the solution is cool you now have a supersaturated solution.
