Question

If a chemist wants to make one liter of a 1.5 M solution of NaOH from a stock solution of 2.5 M NaOH, how many milliliters of the stock solution would the chemist need to use?

A.6.0 x 102 mL

B. 0.60 mL


C. 1.7 x 103 mL

Answer 1

0.60 mL

Step-by-step explanation:

1. Set up the equation using Vi = MfVf / Mi

Vi = (1.5M · 1L) / 2.5M

2. Solve

1.5 / 2.5 = 0.6
