Question

For the given data, calculate the masses, pressure, mols, volume
& gas constant R.

DATA -

(M1) Mass of empty capsule = 0.109g

(M2) Mass of capsule filled with sample = 1.501g

(M3) Mass of system before reaction = 100.5g

(M4) Mass of system after reaction = 99.90g

Temp CO_{2} in celsius = 22

Atmospheric pressure in room = 757

Volume of CO_{2} = 200ml

Calculate >>>

a) Mass: sample in capsule

b) Mass CO_{2}

c) Pressure CO_{2} (g) in Atm [1 atm = 760mm Hg = 101.315
kPa]

d) Mols CO2

e) Gas constant R (Is it 0.08206 always? or does the above data
change this?)

**Please show all calculations**

Answer #1

Information:
In this experiment, you will fill a gelatin capsule with an alloy
sample. If the mass of the gelatin capsule is 0.123 g, and the mass
of the capsule plus alloy sample is 0.215 g, calculate the
mass, in grams, of the alloy sample. - 0.092 g
The alloy sample is dissolved in HCl and
H2
gas
is produced and collected over water. The volume of
H2
gas produced is 89.5 mL. What is the volume of gas, in...

Gases are often stored and shipped in high pressure containers.
Consider a gas tank whose volume is 63.0 gallons and contains N2
gas at a pressure of 17,400 kPa at 21 degrees celsius. What is the
mass of N2 contained in the tank? At what temperature would the
pressure in the tank equal 145.0 atm?

A gas-forming reaction produces 1.65 m3 of gas against a
constant pressure of 196.0 kPa. Calculate the work done by the gas
in joules. Hint: be sure to convert the cubic meters to liters and
kiloPascals to atm. Look up the conversion factors!

± Stoichiometric Relationships with Gases
The ideal gas law
PV=nRT
relates pressure P, volume V, temperature
T, and number of moles of a gas, n. The gas
constant Requals 0.08206 L⋅atm/(K⋅mol) or 8.3145
J/(K⋅mol). The equation can be rearranged as follows to solve for
n:
n=PVRT
This equation is useful when dealing with gaseous reactions because
stoichiometric calculations involve mole ratios.

A second order gas reaction A+B→2R+S proceeds in a
constant pressure batch reactor where its volume increases 25% in 6
minutes. The feed contains 50% inerts and reactants are feed at
stochiometric ratio. If the same reaction takes place in a constant
volume bomb with 3 atm initial pressure at room temperature,
calculate the total pressure after 115 minutes. Take gas constant
as 0,082 L.atm/mol.K.

n this exercise, weighed samples of a solid unknown containing
NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2
liberated by the reaction in the gas phase is measured with a gas
collection syringe. From the volume we can calculate the number of
moles of CO2 in the gas phase using the ideal gas
approximation.
Since the CO2 is generated in an aqueous environment (aqueous
HCl), some CO2 will dissolve in the liquid phase. The amount of...
