Answer:
volume required = 50 mL
Step-by-step explanation:
The concentration of a substance is the quantity of solute present in a given quantity of solution.
In an aqueous solution of hydrochloric acid, the concentration is the number of moles of HCl present in a certain volume (which we are calculating) of solution.
we can write an expression for this:
c = n/V, where c = concentration, n = moles, and V = volume in L.
Rearranging this formula, we get:
V = n/c.
Therefore, V = 0.6 / 12.0 = 0.05 L or 50 mL
