The full question is shown in the image attached to this answer
Answer:
6.2 * 10^-3
Explanation:
The reaction at equilibrium is as follows;
TiCl4(l) → Ti(s)+ 2Cl2(g)
We have to obtain the concentration of chlorine gas as follows;
[Cl2] = 1.08/70.91 g/mol × 5.2 L
[Cl2] = 0.079 M
Kc = [Cl2]^2
Kc = [ 0.079]^2
Kc = 6.2 * 10^-3

<h3>Further explanation</h3>Given
25 ml ethanol
d = 0.789 g/ml
250 ml solution
Required
The molarity
Solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
mass of ethanol :
= 25 ml x 0.789 g/ml
= 19.725 g
mol ethanol :
= 19.725 g : 46 g/mol
= 0.429
The molarity :
= 0.429 : 0.25 L
= 1.716 M
