moles of water in
of water.
Explanation:
Mass of water =
Molar mass of water = M = 18 g/mol
Moles = n =
So, there are moles of water in
of water.
Answer:
Answer is explained in the explanation section below.
Explanation:
Note: This question is not complete and lacks necessary data to solve. However, I have found a similar question and I will be using its data to solve this question for the sake of understanding and concept.
Solution:
Equilibrium Reaction:
CaO(s) + H2O(g) -->Ca(OH)2(s)
We need to find the reaction quotient for this question:
Q =
Here, only the pressure of the gaseous reactant will be used and here H20 is the only reactant which is gaseous.
And we are given that, vapor pressure of water is = 0.106 mmHg
So,
Now, we need to convert it into atm
so, 1atm = 760 mmHg
0.106 mmHg = 0.106/760 atm
0.106 mmHg = 1.394 x atm
Plugging in the values in the equation, we get:
Q =
Q =
Q = 7173.60
