Answer:
Explanation:
Molarity is a measure of concentration in moles per liter.
The molarity of the solution is 1.2 M NaNO₃ or 1.2 moles NaNO₃ per liter. There are 0.25 liters of the solution. The moles of solute are unknown, so we can use x.
- molarity= 1.2 mol NaNO₃/L
- liters of solution=0.25 L
- moles of solute =x
We are solving for x, so we must isolate the variable, x. It is being divided by 0.25 liters. The inverse of division is multiplication, so we multiply both sides by 0.25 L.
The units of liters cancel, so we are left with the units moles of sodium nitrate.
There are 0.3 moles of sodium nitrate.
Answer: At equilibrium, the partial pressure of is 0.0330 atm.
Explanation:
The partial pressure of is equal to the partial pressure of
. Hence, let us assume that x quantity of
is decomposed and gives x quantity of
and x quantity of
.
Therefore, at equilibrium the species along with their partial pressures are as follows.
At equilibrium: 0.123-x x x
Now, expression for of this reaction is as follows.
Thus, we can conclude that at equilibrium, the partial pressure of is 0.0330 atm.
