Answer:
The final solution has a concentration of 5.95 * 10^-6 M
Explanation:
<u>Step 1:</u> data given
Mass of fluoxymesterone : 10mg = 0.01g
Molar mass of fluoxymesterone = 336g/mole
Volume = 500 mL =0.5 L
<u>Step 2:</u> calculate Concentration of fluoxymesterone
Concentration = mole / volume
⇒ To find the concentration, we first need to find the number of moles
⇒moles fluoxymesterone= mass of fluoxymesterone / Molar mass
0.01g / (336g/mole) = 2.976 *10^-5 mole
C = 2.976 *10^-5 mole / 0.5 L = <u>5.95 * 10 ^-5 M</u>
<u>Step 3:</u> Calculate dilution
⇒ If 10 mL is diluted to 100 ml then this is a 10x dilution (100 ml /10 ml = 10) so the final solution will be 10 x more dilute.
⇒5.95 * 10^-5 M /10 = 5.95 ^* 10^-6 M
We can control this through the following formula: M1 * V1 = M2 * V2
5.95 *10^-5 * 10 * 10 *^-3 = M2 *0.1 L
M2 = 5.95 * 10^-6 M
