Explanation:
Given
mass of aluminium kettle(
)=1.05 kg
(a)Heat capacity of the kettle=Heat capacity of Aluminium
(b)Heat is required to increase the temperature of this kettle from 
Q=71.82 kJ
(c)If kettle contains water 1.25 L of water i.e. 1.246 kg of water then heat required to raise the temperature from 23 to 99
Q=71.82+396.20=468.028 kJ

Answer: 0.52 L of 15 M 
will be used to prepare this amount of 0.52 M base.
Explanation:
But on diluting the number of moles remain same and thus we can use molarity equation.
(to be prepared)
where,
=concentration of stock solution = 15 M
= volume of stock solution = ?
= concentration of solution to be prepared = 0.52 M
= volume of solution to be prepared = 15 L
Thus 0.52 L of 15 M will be used to prepare this amount of 0.52 M base
