Question

You place 10 grams of Carbon dioxide gas,0.260 ,moles of Xenon gas and 3.50 X 10^23 atoms of neon gas in a cylindrical piston at STP condition.s. The gas is pumped in at the base of the sylinder causing the piston to rise such that the pressurein the sylinder remains 1 atmosphere of pressure.

a) calculate the mass of the mixture

b) calculate the density of the gas mixture answer in g/L

c) calculate the distance fo the piston above the cylinder

base, id the radius is 25.00 cm

d) the piston is pushed down until it is 5.00 cm from the base of the cylinder, determine the density of the gas mixture at this new condition.
