Question

f I add 45 mL of water to a 105 mL of a 0.25 M NaOH solution, what will be the molarity of the diluted solution be?

Answer 1

0.175M or 0.18M with correct significant figures

Step-by-step explanation:

use the equation M1×v1=M2×v2 where M1= 0.25M, V1= 105mL or 0.105L, and V2= 105mL+45mL (150mL or 0.150L)

(0.25M×0.105L)÷0.150L = M2
