Answer:
A
Step-by-step explanation:
To determine the volume required to dilute a 1.0 L solution of 6.0 M HCl to a 0.2 M solution, we can use the equation for dilution:
M1V1 = M2V2
Where:
M1 = Initial concentration of the solution (6.0 M)
V1 = Initial volume of the solution (1.0 L)
M2 = Final concentration of the solution (0.2 M)
V2 = Final volume of the solution (unknown)
Rearranging the equation, we have:
V2 = (M1/M2) * V1
Plugging in the values:
V2 = (6.0 M / 0.2 M) * 1.0 L
V2 = 30 L
Therefore, the volume required to dilute the 1.0 L solution of 6.0 M HCl to a 0.2 M solution is 30 liters (option a).
