Explanation:
To know the temperature at which KCl dissolves in water we need to refer to the general solubility curves.
In the case of , of it will dissolve in of water at a minimum temperature of .
So, the the minimum temperature needed to dissolve 35 grams of KCl in 100 grams of water is .
Answer:
Molarity of solution is 0.0049 M
Explanation:
Molarity of a solution is the ratio of number of moles of solute to volume of solution in Liter
Number of moles is the ratio of mass to molecular weight of a compound.
Here is the solute.
448 mg of = 0.448 g of
So, 0.448 g of = moles of = 0.00245 moles of
Total volume of solution = 500 mL = 0.5 L
So, molarity of solution =
