Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.
From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm
18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
Answer: I believe the answer is B. Sorry if i'm wrong
Explanation:
Answer : The value of
of the generic salt is, 
Explanation :
As we are given that, a solubility of salt is, 8.70 g/L that means 8.70 grams of salt present in 1 L of solution.
First we have to calculate the moles of salt 

Molar mass of
= 345 g/mol

Now we have to calculate the concentration of 
The equilibrium chemical reaction will be:

Concentration of
= 
Concentration of
= 
The solubility constant expression for this reaction is:
![K_{sp}=[A^{2+}][B^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BA%5E%7B2%2B%7D%5D%5BB%5E-%5D%5E2)
Now put all the given values in this expression, we get:


Thus, the value of
of the generic salt is, 
<u>Answer:</u> The solubility of chromium (III) iodate is 
<u>Explanation:</u>
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
The chemical equation for the ionization of chromium (III) iodate follows:
s 3s
The expression of
for above equation follows:

We are given:

Putting values in above expression, we get:

Hence, the solubility of chromium (III) iodate is
