- A cylinder containing 100g of an ideal gas (mol.wt =40g/mol) at 27 degree celcius and 2atm pressure falls on a transit and develops a dent. If 10g of the gas leaks out on the fall because the valve attached to the cylinder cannot keep the pressure greater than 2atm and the temperature remains constant during the process. 1) calculate the volume of the cylinder before and after the fall? 2) Had the valve been pretty strong such that there is no leakage of gas, what will be the pressure of the dent?

Relationship between P and V when T and n are constant Complete the data in the pressure column in the table below for the pressure of the confined gas. Then, plot the data, placing pressure in mm Hg on the ordinate (y axis) (range 500 mm Hg to 1000 mm Hg) and volume on the abscissa (x axis) (range 25ml to 51mL). Choose increments such that the graph will take up at least half of the graph paper.arrow_forwardThe label has come off a cylinder of gas in your laboratory. You know only that one species of gas is contained in the cylinder, but you do not know whether it is hydrogen, oxygen, or nitrogen. To find out, you evacuate a 5-liter flask, seal it and weigh it, then let gas from the cylinder flow into it until the gauge pressure equals 1.00 atm. The flask is reweighed, and the mass of the added gas is found to be 13.0 g. Room temperature is 27°C, and barometric pressure is 1.00 atm. What is the gas?arrow_forward
