A square and rectangle because they are parcélele
Neon = app. 20.1795 g/mol
<span>Bromine = app. 79.904 g/mol </span>
<span>-----> 79.904 g/mol / 20.1795 g/mol = 3.96 (Close to 4) </span>
<span>Using Moles In 1000 g </span>
<span>1000 g / 20.1795 g/mol = app. 49.555 mol of Ne </span>
<span>1000 g / 79.904 g/mol = app. 12.515 mol of Br </span>
<span>-----> 49.555 mol / 12.515 mol = 3.96 (Close to 4) </span>
<span>Using Avogadro's Number </span>
<span>49.555 mol x 6.022x10^23 atoms = app. 2.984x10^25 atoms of Ne </span>
<span>12.515 mol x 6.022x10^23 atoms = app. 7.537x10^24 atoms of Br </span>
<span>-----> 2.984x10^25 / 7.537x10^24 = 3.96 (Close to 4) </span>
<span>So no matter how you look at it or calculate it, the answer is always the same. </span>
<span>I hope it helps!</span>
The go super slow and sometimes so slow that you can't even tell they are moving. PLZ give me the brainliest answer. I hope I helped! :):):)
Answer:
C
Explanation:
The number of particles of any kind in 1 mol is 6.02*10^23.
How you modify that depends on the units.
The number of molecules in 1 mole of hydrogen is 6.02*10^23 molecules.
Each molecule consists of 2 atoms. Pure hydrogen at STP will have a multiplier of 2.
So the number of atoms is 2*6.02 * 10^23 = 1.20 * 10^24 atoms.
