Answer:
2 moles of solute.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution.
Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.
Molarity =
For 1 litre of solution 1 mole of solute is required to make a one molar solution.
Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.
Answer : The concentration of at equilibrium is 0 M.
Solution : Given,
Concentration of = 0.0200 M
Concentration of = 1.00 M
The given equilibrium reaction is,
Initially conc. 0.02 1.00 0
At eqm. (0.02-x) (1.00-3x) x
The expression of will be,
By solving the term, we get:
Concentration of at equilibrium = 0.02 - x = 0.02 - 0.02 = 0 M
Therefore, the concentration of at equilibrium is 0 M.
