What guidelines were used by Miller and Urey when they constructed their experiment?
1 answer:
<u>Guidelines used by Miller and Urey:</u>
In 1952, Stanley Miller with the support of Harold Urey conducted the classic experiment investigating the original evolution of life from chemical substances. (abiologically)
Miller and Urey conducted experiments by setting up an apparatus trying to provide the proof that organic compounds can exist from inorganic compounds. His apparatus had conditions nearly similar to the time of life started and by the flow of electricity which had water , methane
, ammonia
, and hydrogen
obtaining various organic molecules.

Answer : The volume of 4.9 M stock solution used to prepare the solution is, 12.24 ml
Solution : Given,
Molarity of aqueous solution = 1.20 M = 1.20 mole/L
Volume of aqueous solution = 50.0 ml = 0.05 L
(1 L = 1000 ml)
Molarity of stock solution = 4.9 M = 4.9 mole/L
Formula used :
where,
= Molarity of aqueous
solution
= Molarity of
stock solution
= Volume of aqueous
solution
= Volume of
stock solution
Now put all the given values in this formula, we get the volume of stock solution.
By rearranging the term, we get
Therefore, the volume of 4.9 M stock solution used to prepare the solution is, 12.24 ml
