Answer:
0.0250 g
Explanation:
Step 1: Determine the molar mass of Vitamin C.
The molar mass is the mass in grams corresponding to 1 mole. In order to calculate the molar mass of vitamin C (C₆H₈O₆) we need to add the molar masses of the elements that compose it.
M(C₆H₈O₆) = 6 × M(C) + 8 × M(H) + 6 × M(O)
M(C₆H₈O₆) = 6 × 12.01 g/mol + 8 × 1.01 g/mol + 6 × 16.00 g/mol
M(C₆H₈O₆) = 176.14 g/mol
Step 2: Calculate the mass corresponding to 0.000142 mol of vitamin C.
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,
