All real gases deviate to some extent from the behavior of ideal gases. at standard conditions, the density of o_2 gas is 0.0014290 g/ml, that of h_2 gas is 0.8988 g/ml, and that of co_2 is 0.0019769 g/ml. using these values and the molecular weights from your textbook (in g/mol, not rounded off), calculate the molar volume of each of these, in ml/mol, to five significant figures. the molar volume of an ideal gas is 22414 ml/mol. based on the previous three calculations, which of the previous gases has its molar volume deviate the most from that of an ideal gas?

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
