The value of molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp is 80 g/mol.
What is ideal gas law?The ideal gas law can be given as,
[tex]pV=nRT[/tex]
Here, (p) is pressure, (V) is volume, (n) amount of substance, (R) is ideal gas constant and (T) is the temperature.
For the given problem the modified ideal gas law, (written below) can be used.
[tex]PM=dRT[/tex]
Here, (M) is molar mass and (d) is density.
The molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp. As the density is ratio of molar mass to volume. Thus,
[tex]d=\dfrac{40}{11.2}\\d=3.57\rm\; g/L[/tex]
The standard value of temperature and pressure is,
[tex]T=273\text{ K}\\p=1\rm\; bar[/tex]
The value of ideal gas constant (R) is 0.0821 atmL per mol K. Put these values in the above formula,
[tex]1\times M=3.57\times0.0821\times273\\M=80\rm\; g/mol[/tex]
Thus, the value of molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp is 80 g/mol.

A news article reported that college students who have part-time jobs work an average of 15 hours per week. The staff of a college newspaper thought that the average might be different from 15 hours per week for their college. Data were collected on the number of hours worked per week for a random sample of students at the college who have part-time jobs. The data were used to test the hypotheses
The Confidence Interval of the given random sample survey is gotten as; CI = 13.755 ± 1.456
What is the confidence Interval?We are given the hypotheses as;
Null Hypothesis; H₀: μ = 15
Alternative Hypothesis; Hₐ: μ ≠ 15.
where μ is the mean number of hours worked per week for all students at the college with part-time jobs.
We are told that it has a 95% confidence interval and degree of freedom of df = 25
From the t-table, the t-score = 2.06
The table gives us the standard error as 0.707 and sample mean of 13.755. Thus, we can find the confidence interval as;

Acetylene, c2h2 c 2 h 2 , can be converted to ethane, c2h6 c 2 h 6 , by a process known as hydrogenation. the reaction is c2h2(g)+2h2(g)⇌c2h6(g) c 2 h 2 ( g ) + 2 h 2 ( g ) ⇌ c 2 h 6 ( g ) given the following data at standard conditions (all pressures equal to 1 atm a t m and the common reference temperature 298 k k ), what is the value of kp k p for this reaction?
The value of the Kp is obtained from Kp = p.C2H6/p.C2H2 * pH2^2 as 1.
What is Kp?The Kp is the equilibrium constant for a gas phase reaction we have to put down the equation for the Kp here as; Kp = p.C2H6/p.C2H2 * pH2^2.

An ellipse is represented by the equation . each directrix of this ellipse is a ________________________ from the center on the major axis.
The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.
How to determine the distance of the directrix?The equation of the ellipse is given as:
[tex]\frac{(x - 5)^2}{625} -\frac{(y - 4)^2}{225} =1[/tex]
The above means that:
a^2 = 625
a = 25
b^2 = 225
b = 15
Calculate c using:
c^2 = a^2 - b^2
This gives
c^2 = 625 - 225
Evaluate the difference
c^2 = 400
Evaluate the square root
c = 20
The equation of the directrix is
x - x₀ = ± a²/c
So, we have:
x - x₀ = ± 625/20
Evaluate the quotient
x - x₀ = ± 31.25
This means that, each directrix is 31.25 units from the center on the major axis.
