The best and most correct answer among the choices provided by the question is the second choice "<span>the moon’s orbital period and distance from Earth"
</span> <span>The Earth's mass is </span>5.9736<span> x 10</span>24<span> kg. That's a big number, so let's write it out in full: 5,973,600,000,000,000,000,000,000 kg. You could also say the Earth's mass is </span>5.9<span>sextillion tonnes. Phew, that's a lot of mass.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
H₂ will have the highest average kinetic energy
<h3>Further explanation </h3>
Energy because this motion is expressed as Kinetic energy (KE) which can be formulated as:
Average velocities of gases can be expressed as root-mean-square averages. (V rms)
R = gas constant, T = temperature, Mm = molar mass of the gas particles
From the two equations above, it can be concluded
- KE is directly proportional to gas velocity
- Gas velocity is inversely proportional to molar mass
So <em>the highest KE is owned by the gas with the smallest molar mass</em>
<em />
Molar mass of the gas :
A) H₂ : 2 g/mol
B) N₂ : 28 g/mol
C) O₂ : 32 g/mol
D) F₂ : 38 g/mol
So <em> H₂ has the highest average kinetic energy</em>
Answer:
<h2>14.05 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>14.05 moles</h3>
