Question

If you allow one pound of carbon dioxide to sublime (change from CO_2 (x) to CO_2 (g) at room conditions of roughly I atom and 25 degree C, what volume would it occupy? In part 2 of this experiment, the assumption was made that the air in the flask was dry air. What happens to the mass of air when water vapor is introduced at the same pressure and volume? If the air was moist (which it certainly was, to some extent), how would this have affected your results? The three top components of natural gas are methane (CH_4), ethane (C_2H_6) and propane (C_3H_8). Given your result for molar mass, which do you think is the most prevalent of the three compounds?

Explanation / Answer

1. No of mol of Co2   = 453.592/44 = 10.31 mol (1 pound = 453.592 grams)

   volume of CO2 = nRT/P

= 10.31*0.0821*298/1

= 252.242 L

2. it needs experiment details

3. CH4 molarmass = 16 g/mol

   C2H6 = 30 g/mol

   C3H8 = 44 g/mol

if molarmass increases , rate of diffusion decreases.so that

most prevalent gas is CH4(methane)
