Answer:
m = 29.6 grams
Explanation:
Given that,
Number of moles = 0.540
The molar mass of manganese = 54.93 g/mol
We know that,
Number of moles = given mass/molar mass
So, the required mass of the Manganese is equal to 29.6 grams.

Answer: There are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
Explanation:
Given: = 2.25 L, = 9.0 mol
= 1.85 L, = ?
Formula used to calculate the moles of helium are as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
The partial pressure of CO is 0.536 atom.
<h3>Further Explanation</h3>
Dalton's Law of Partial Pressure states that the total pressure of a mixture of non-reacting gases is equal to the sum of the partial pressures of the individual gases. Mathematically, it can be represented as follows:
If the total pressure is known as well as the number of moles of the gases in the mixture, the partial pressure of a component as can be calculated using the equation below:
where:
Pₓ is the partial pressure of gas X
P(total) = total pressure of the mixture
nₓ = number of moles of gas X
n(total) = total number of moles of gas
To solve the problem, first sort the given:
- n(total) = 0.220 mol CO + 0.350 mol F₂ + 0.640 mol He = <u>1.21 moles</u>
- n(CO) = 0.220 mol
- P(total) = 2.95 atm
Then we plug in the given values into the equation above:

Answer:
Hydrated form of hexafluoroacetone is highly stable.
Explanation:
Hydrated form of hexafluoroacetone is highly stable due to presence of two five membered ring structures formed through hydrogen bonding between F and H (in -OH group).
Due to this stable structure, can not escape the hydrated form and goes back to keto form.
The structure of hydrated form of hexafluoroacetone has been shown below.
