1. Give reasons why the helium atom is smaller than the cesium atom. 2. A student got a problem wrong. They were asked, “How many grams of MgCl2 (molar mass = 95.21 g/mol) are needed to make 3.16 L of a 0.500 M MgCl2 solution?” The correct answer is 150. but the student got 1.58. What mistake did the student make? 3. To solve the following problem what is the reason you must subtract the vapor pressure of water, 24 torr, from the total pressure, 747 torr in order to solve the problem? “A 500.0-mL sample of H2 gas is collected over water at 298 K and 747 torr. What volume would the dry H2 gas occupy at STP? (Given: the vapor pressure of water at 298K is 24 torr).” By the way, the answer is .436 liters. NOTE: I am not asking you to solve this problem. I am asking the reason for subtracting the vapor pressure. If you simply solve the problem, you will get no points.
