An empty vial has a mass of 67.77 g. If the vial has a mass of 244.56 g when completely filled with liquid carbon terachloride (d = 1.59 g/cm3), what is the volume of the vial?
What would the mass of the vial be if it was now filled with water at 25o C (d = 0.997 g/cm3)?
If 6.06 L of O2 gas is collected over water at 250C (vapor pressure = 23.8 torr) and a barometric pressure of 702 torr, what is the mass of H2O2 (MM = 34.02 g/mole) decomposed?
