Explanation:
As it is given that both the given containers are at same temperature and pressure, therefore they have the same density.
So, mass of in container- 1 is as follows.
5.35 mol x molar mass of
= 7.61 mol x 146.06 g/mol
= 1111.52 g
Therefore, density of will be calculated as follows.
Density =
density =
= 0.532 g/mL
Now, mass of in container- 2 is calculated as follows.
4.46 L x 1000 mL/L x 0.532 g/mL
= 2372.72 g
Hence, calculate the moles of moles present in container 2 as follows.
No. of moles =
=
= 16.24 mol
Since, 1 mol contains 6 moles F atoms
.
So, 16.24 mol contains following number of atoms.
=
= 97.46 mol
Thus, we can conclude that moles of F atoms in container 2 are 97.46 mol.
Answer:
<h2>The answer is 2.34 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 7.5 g
volume = 3.2 mL
The density is
We have the final answer as
<h3>2.34 g/mL</h3>

Answer:
a. 94 g of Mn
b. 0.239 g of He
c. 6.69ₓ10⁻⁸ g of N
d. 1.14ₓ10⁻⁶ g of U
Explanation:
This is the way to make the conversions:
Number of atoms → Moles of element → grams
We begin from the information that: 1 mol of atoms has 6.02×10²³ (NA) atoms
Let's convert all the numbers to amount of moles (number of atoms / NA)
a. 1.03 x 10²⁴ of Mn / 6.02×10²³ = 1.71 moles of Mn
b. 3.60 x 10²² of He / 6.02×10²³ = 0.0598 moles of He
c. 2.88 x 10¹⁵ of N /6.02×10²³ = 4.78ₓ10⁻⁹ moles of N
d. 2.88 x 10¹⁵ of U /6.02×10²³ = 4.78ₓ10⁻⁹ moles of U
We convert the moles to mass (moles . molar mass)
a. 1.71 moles of Mn . 54.94 g /1mol = 94 g of Mn
b. 0.0598 moles of He . 4 g /1mol = 0.239 g of He
c. 4.78ₓ10⁻⁹ moles of N . 14 g /1mol = 6.69ₓ10⁻⁸ g of N
d. 4.78ₓ10⁻⁹ moles of U . 238.03 g /1mol = 1.14ₓ10⁻⁶ g of U

Explanation:
The reaction of 1-bromo-2-tert-butylcyclohexane with potassium tert-butoxide is an elimination reaction that occurs by E2 mechanism.
The E2 reaction proceeds faster when the hydrogens are in an antiperiplanar position at an angle of 180 degrees.
This is only attainable in the trans isomer of 1-bromo-2-tert-butylcyclohexane. Hence trans 1-bromo-2-tert-butylcyclohexane reacts faster with potassium tert-butoxide
