Agas storage cylinder in an ordinary chemical laboratory measures 4.4 cm wide and 17.cm high. this is the label on it. contents: n2 gaspressure: 29.8 atmif the cylinder is opened and the gas allowed to escape into a large empty plastic bag, what will be the final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder? write your answer in liters. round your answer to 2 significant digits.

Explanation:

We assume equal number of moles at constant temperature. Therefore,  

Hence,

where,     = atmospheric pressure = 1 atm

                = volume bag + volume gas left over in cylinder.

Also we know that formula for volume of cylinder is as follows,

                            V =

It is given here that, diameter of cylinder = 4.4 cm

Therefore, radius =

                             = 2.2 cm

and, h =17 cm

Hence, calculate value of as follows.

                          = 7.7 L

Thus, we can conclude that final volume of nitrogen gas, including what's collected in the plastic bag and what's left over in the cylinder is 7.7 L.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

the correct answer would be d. hope this !
