To find the volume of 4.7 M sodium hydroxide needed to neutralize 2.0 L of 1.0 M hydrochloric acid, we can use the equation:

M1V1 = M2V2

Where:
M1 is the molarity of the acid (1.0 M)
V1 is the volume of the acid (2.0 L)
M2 is the molarity of the base (4.7 M)
V2 is the volume of the base (what we want to find)

Rearranging the equation, we get:

V2 = (M1V1) / M2

Substituting the values, we get:

V2 = (1.0 M * 2.0 L) / 4.7 M

V2 ≈ 0.43 L

So the volume of 4.7 M sodium hydroxide needed to neutralize 2.0 L of 1.0 M hydrochloric acid is approximately 0.43 L.

Therefore, the answer is option a. 0.43 L.
