<span>If you give it a good search, the most used answer would probably be as follows,
</span><span>In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.

According to Gayle Lusac's law, pressure is proportional to absolute temperature of a gas. Thus:
P/T = constant
So if the temperature becomes 3T, the pressure would increase to 3P

Resonance StructureEnergy (kJ/mol)[S-C N]--23.00[S=C=N]
Answer:
<h2>1.16 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>1.16 moles</h3>
Hope this helps you
