Answer: 2.4 ml
Solution :
Molar mass of
= 17 g/mole
Given,: 28% w/w of
solution means 28 g of ammonia in 100 g of solution.
Mass of solution = 100 g
Now we have to calculate the volume of solution.
Molarity : It is defined as the number of moles of solute present in one liter of solution.

where,
n = moles of solute 
= volume of solution in liter = 0.11 L
Now put all the given values in the formula of molarity, we get

Using molarity equation:

Hello,
In this case, as the copper's heat loss is gained by the water, the following energetic relationship is:

Therefore the equilibrium temperature shows up as:

Thus, by knowing that water's heat capacity is 4.18J/g°C, one obtains:
