Answer: The final pressure is 116kPa or
Explanation:
The combined gas equation is,
where,
= initial pressure of gas =
= final pressure of gas = ?
= initial volume of gas = v ml
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 116kPa or
Nitrogen trifluoride is the inorganic compound with the formula NF3. This nitrogen-fluorine compound is a colorless, odorless, nonflammable gas. It finds increasing use as an etchant in microelectronics.

The similarity between first quarter moon and third quarter moon, is the moon is located perpendicular to Earth and the sun.
<h3>What is first quarter moon?</h3>
The first quarter moon is a primary moon phase when half of the moon's face is lit up.
The first quarter moon rises around midday and is visible in the day sky.
<h3>What is third quarter moon?</h3>
Third quarter moon is when the opposite half of the moon is illuminated compared to the first quarter moon. It is the last quarter moon of a lunar month.
<h3>Similarity between
first quarter moon and third quarter moon?</h3>
The similarity between first quarter moon and third quarter moon, is the moon is located perpendicular to Earth and the sun.
Thus, the similarity between first quarter moon and third quarter moon, is the moon is located perpendicular to Earth and the sun.

Answer:
0.06mole
Explanation:
Given parameters:
Volume of balloon = 2.5L
T = 343.5K
P = 66.7kPa; in atm gives = 0.66atm
Unknown:
Number of moles of He = ?
Solution:
To solve this problem, we use the ideal gas equation.
It is mathematically expressed as;
Pv = nRT
where p is the pressure
v is the volume
n is the number of moles
R is the gas constant
T is the temperature
0.66 x 2.5 = n x 0.082 x 343.5
n = 0.06mole
