<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 (H_2O), methane \left(\mathrm{CH}_{4}\right), ammonia \left(\mathrm{NH}_{3}\right), and hydrogen \left(\mathrm{H}_{2}\right) obtaining various organic molecules.

How many moles of potassium are in 3.78 x 10^21 atoms of K?
lbvjy [14]

Answer: 6.3 x 10^-3 moles

Explanation:

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of potassium = 6.02 x 10^23 atoms

Z moles = 3.78 x 10^21 atoms

To get the value of Z, we cross multiply:

(3.78 x 10^21 atoms x 1mole) = (6.02 x 10^23 atoms x Z moles)

3.78 x 10^21 = (6.02 x 10^23 x Z)

Z = (3.78 x 10^21) ➗ (6.02 x 10^23)

Z = 0.63 x 10^-2)

Place the result in standard form

Hence, Z = 6.3 x 10^-3 moles

Thus, there are 6.3 x 10^-3 moles of potassium in 3.78 x 10^21 atoms of K.
