A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 283 mL at a pressure of 745 torr and temperature of 28.0oC. The vapor pressure of water at 28.0oC is 0.0372 atm. 1. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP. Tries 0/99 The mass of the dry gas is 905 mg. A fragment of the tank indicates that the gas is a monoatomic element. 2. Write out the full name of the gas.
Answers
Answer:
See explanation
Explanation:
From the information given;
We convert the pressure from torr to atm as follows;
745 torr * 1 atm/760 torr = 0.98 atm
Initial pressure P1 = 0.98 atm - 0.0372 atm = 0.9428 atm
Initial volume V1= 283 mL
Initial temperature T1 = 28.0oC + 273 = 301 K
Final volume V2 = ??
Final Temperature T2 = 273 K
Final pressure P2 = 1 atm
From the general gas equation;
P1V1/T1 = P2V2/T2
P1V1T2 = P2V2T1
V2 = P1V1T2/P2T1
V2 = 0.9428 * 283 * 273/1 * 301
V2 = 241.99 mL or 0.24 L
If 1 mole of gas occupies 22.4 L
x moles of gas occupies 0.24 L
x = 1 mole * 0.24 L/ 22.4 L
x = 0.0107 moles
But number of moles = mass/molar mass
molar mass = mass/number of moles
molar mass = 905 * 10^-3g/0.0107 moles
molar mass = 84 g/mol

2.7
Method B Density values
2.703,2.701,2.705,5.811
Density of aluminium [tex]p_d=2.702 g/cm^3[/tex].
a)
Generally the average density for each method is mathematically given by

Generally the standard deviation [tex]\sigma[/tex] for each method is mathematically given by
Method A
[tex]\sigma=\sqrt{\frac{\sum(x-a)^2}{N} }[/tex]

Imagine that you have an ideal gas in a 5.80 L container, and that 2950 molecules of this gas collide with a square-centimetre area of the container at any given instant.
If the volume is increased to 46.4 L at constant temperature, how many collisions will occur per square centimetre of this larger container?
Answers
Answer:
23,600 collisions.
Explanation:
Hello there!
In this case, according to the Avogadro's law, which help us to understand the molecules-volume relationship as directly proportional:
[tex]\frac{molecules_2}{V_2}=\frac{molecules_1}{V_1}[/tex]
It is possible for us to compute the collisions once the volume is increased as shown below:
[tex]molecules_2=\frac{molecules_1V_2}{V_1}\\\\molecules_2=\frac{2950*46.4L}{5.80L}\\\\molecules_2=23600[/tex]
Which means 23,600 collisions will occur per square centimeter.

Two students come up with an idea they think will save time: We just used the fast titrations. You can stop the video when the solution turns pink. We know that when the solution turns pink, the titration is complete, so we just read the volume from the burette as soon as it turns pink. This is faster than going through all the shorter videos and works just as well. Is this method just as accurate as using the slow titrations
Answers
Answer:
Yes.
Explanation:
Yes, this method is accurate just as the slow titration because in both type of titrations we want to measure the point at which the indicator change the colour of the solution. Both fast and slow titrations are the same in their function i.e. both tell us the point or the amount at which the indicator change the colour of the solution so we can conclude from this discussion that fast titration gives the same result just as the slow titration.
