Answer:
AuCl
Explanation:
Given parameters:
Mass of Gold = 2.6444g
Mass of Chlorine = 0.476g
Unknown:
Empirical formula = ?
Solution:
Empirical formula is the simplest formula of a compound. Here is the way of determining this formula.
Elements Au Cl
Mass 2.6444 0.476
Molar mass 197 35.5
Number of moles 2.6444/197 0.476/35.5
0.013 0.013
Divide by the
smallest 0.013/0.013 0.013/0.013
1 1
The empirical formula of the compound is AuCl
Answer: = 1.834 M
= 0.004 M
= 0.166 M
Explanation:
Initial concentration of = 0.15 M
Initial concentration of = 2.0 M
The given balanced equilibrium reaction is,
Initial conc. 2 M 0.15 M 0
At eqm. conc. (2-x) M (1-6x) M (x) M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
By solving the term 'x', we get :
= (2-x) = 2-0.166 = 1.834 M
= (1-6x) = 1-6(0.1660)= 0.004 M
= x = 0.166 M
