You have a tank of helium with a volume of 10 liters that is currently 35 atm of pressure. If you open the valve on the tank and release the helium into a room with a volume of 10,000 liters, what will happen to the "space" between the helium atoms? Clearly explain
The temperature remains unchanged. Determine the final pressure of the system of two tanks.
A sample of oxygen gas at a pressure of 0.996 atm and a temperature of 195oC, occupies a volume of 714 mL. If the gas is cooled at constant pressure until its volume is 544 mL, the temperature of the gas sample will be oC.

If you mix 10.0 grams of CH3SH with excess CO and 8.65 grams of CH3COSCH3 is produced, what is the percent yield of the CH3COSCH3?
What is the boiling point of the solution produced by adding 363 g of ethylene glycol (molar mass = 62.1 g/mol) to 1.5 kg of water? For each mole of nonvolatile solute, the boiling point of 1 kg of water is raised 0.51°C.
2.9 mol Fe(OH)3 and 7.7 mol H2SO4 react according to the equation 2 Fe(OH)3 + 3H2SO4 ->Fe2(SO4)3 + 6H2O. If the limiting reactant is Fe(OH)3, calculate the amount of Fe2(SO4)3 formed.
