Calculate the work done in joules, when 4.5 L of argon expands to 11 L at constant temperature against an external pressure 545 torr.
A sample of zinc metal reacts completely with an excess of hydrochloric acid: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) The gaseous product is collected over water at 25.0oC and barometric pressure of 0.980 atm.
What is the theoretical yield of aspirin if 190 kg of salicylic acid is allowed to react with 128 kg of acetic anhydride?
53.5 g of an ideal gas of molecular weight = 30.5 g/mol are confined at a pressure of 133 mmHg. The density of the gas is 0.228 g/L. Compute the temperature of the gas in degrees Celsius.
