A 2.00-g sample of white solid was vaporized in a 345-mL vessel. If the vapor has a pressure of 985 mmHg at 158°C, what is the molecular mass of the solid?
Determine the partial pressure and the total pressure using Dalton's law of partial pressures - Determine the total pressure of the mixture.
When NO(g) reacts with H2(g) to form N2(g) and H2O(l), 376 kJ of energy are evolved for each mole of NO(g) that reacts. Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation.
