Answer:
16 g/mol
Explanation:
In CO2, it means we have 1 mole of carbon and 2 moles of oxygen.
However, we want to find the molar mass of just a single mole of oxygen.
Now, from tables of values of elements in electronic configuration, the molar mass of oxygen is usually approximately 16 g/mol.
In essence the molar mass is simply the atomic mass in g/mol
<span>In a salt solution (a solution of water (H2O) and Salt, chemical formula NaCl), the positively charged Hydrogen atoms from water form bonds with the negatively charged Chloride atoms of Salt (which is the formulate NaCl), and the negatively charged oxygen atom of water (one atom per water molecule) form a bond with the positively charged Sodium ions (Na) of salt.</span>
Answer : The equilibrium constant for this reaction is, 
Explanation :
The given main chemical reaction is:
; 
The intermediate reactions are:
(1) 
; 
(2) 
; 
We are reversing reaction 1 and multiplying reaction 2 by 2 and then adding both reaction, we get:
(1) 
; 
(2) 
; 
Thus, the equilibrium constant for this reaction will be:
Thus, the equilibrium constant for this reaction is,
