The reasons the above options are correct are as follows:
p) The factors that affect the rate at which a solute dissolves are;
The surface area of the solute, especially when in solid state
The temperature of the system
The measure of steering applied
Therefore, the rate at which a solute dissolves is not related to the mass or quantity of the of the which can dissolve
