Answer:

14 ml of water

Explanation:

To find the volume you need to dilute the concentration of a solution, you should use the formula C1 x V1 = C2 x V2 in which:

C1 = initial concentration ( in this case 60 %)

V1 = initial volume ( in this case 70 ml)

C2 = Final concentration ( you want to dilute until 50 %)

V2 = final volume ( the variable you want to search)

So you need to:

1.- Isolate the variable you want to find: V2 = (C1 x V1) / C2

2.- Substitute data: V2 = (60% x 70 ml) /50 %

3.- You do the math, in this case is 84 ml.

4.- Remember that you have a initial volume of 70 ml, so the difference (84 ml - 70 ml = 14 ml) is the volume you need to add to dilute your solution.

I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture. 

Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>
