Answer:
2.60 moles of A remaining.
Explanation:
According to Le Chatelier's principle, the equilibrium would shift if the volume, concentration, pressure, or temperature changes.
In this question, we were told that the volume doubles, that implies that we would have to double the molarity of B/ C (since B=C.)
However, it is obvious and clear from the given equation of the reaction that A is solid in it's activity = 1. Hence, it is then ignored.
So doubling B would be 1.30 M × 2 = 2.60 M
i.e 2.60 M moles of A was consumed.
Now; the number of moles of A remaining is 5.20 - 2.60 = 2.60 moles of A remaining.
1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution. Details about molarity can be found below.
<h3>How to calculate molarity?</h3>
The number of moles of a solution can be calculated by multiplying the molarity of the solution by its volume. That is;
no of moles = molarity × volume
According to this question, a solution has a molarity of 8.20M and volume of 125 mL of solution.
no of moles = 8.20 × 0.125
no of moles = 1.025moles
Therefore, 1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution.

Cover your mouth and nose with a face mask or other material (such as a scarf or handkerchief) until the fallout cloud has passed.
Oh man. Silver coating to dampen radiating heat is great but that, of course does not tell you the temperature of the fluid inside; I would definitely add a small thermostat somewhere around the exterior. that's the only improvement I would suggest, as a standard for all.
The Molarity of solution that contain 2.3 mole of NaCl in 0.45L of solution is calculated using the below equation
= molarity = moles/volume in liters
= 2.3 moles/0.45 L = 5.1 M
