The bright light that comes from a flash bulb is due to a quick combustion of magnesium, according to the following chemical equation: 2Mg (s) + O2(g) → 2MgO (s) If a flashbulb contains 1.3 g of Mg, what is the minimum pressure of O2 needed to burn up that magnesium? Assume the flashbulb has a volume of 10.0 mL and a temperature of 25 oC.
