Question

What volume of a 5.0M solution is needed to make 1.5L of 2.0M NaOH?

a) 0.6L
b) 1.5L
c) 3.0L
d) 7.5L

Answer 1

To make 1.5L of a 2.0M NaOH solution, you will need a) 0.6L of a 5.0M NaOH solution.

Step-by-step explanation:

To determine the volume of a 5.0M solution needed to make 1.5L of 2.0M NaOH, we can use the formula for dilution:

M1V1 = M2V2

Where M1 and V1 are the initial concentration and volume, and M2 and V2 are the final concentration and volume.

Plugging in the given values, we have:

(5.0M)(V) = (2.0M)(1.5L)

Simplifying the equation:

V = (2.0M)(1.5L)/(5.0M) = 0.6L

Therefore, the volume of a 5.0M solution needed to make 1.5L of 2.0M NaOH is 0.6L.
