Answer to Question #155384 in General Chemistry for Snowy Morudu

Question

 What is the concentration of the resulting solution if 50.00 mL of a 1:5 (w/V) solution of chlorpromazine hydrochloride is diluted to 250 mL?

Answer 1

$M1 = \frac{(1.5)\times10}{318.86} = 0.047 M$

for dilution

V1M1 = V2M2

$50\times0.047 = 250\times M2$

$M2 = \frac{0.047}{5} = 0.0094 M$
