Step 1

We have the pressure, volume, and temperature of the oxygen gas, so we can use the Ideal Gas Law to find the number of moles of oxygen gas. The Ideal Gas Law is given by: PV = nRT where P is the pressure, V is the volume, n is the number of moles, R is the gas Show more…

The thermal decomposition of potassium perchlorate to produce potassium chloride and oxygen takes place at approximately 610 °C. KClO4 → KCl + 2O2 The evolved oxygen from this reaction is captured and compressed into a 500.0 mL container, which is stored at 5 °C. If the pressure gauge on the container reads 5120 mmHg, how many moles of oxygen gas are present? Note: To be autoscored correctly, your answer must be entered in standard form, containing only digits and a decimal point (without using exponential notation or including units).
