I need help with question 1 and 2
he following reaction illustrates the decomposition of hydrogen peroxide (H2O2) to form water and oxygen gas:2 H2O2 (l) → 2 H2O (l) + O2 (g)When this reaction is carried out, 0.50 L of O2 gas is collected over water at a total pressure of 1.05 atm. The temperature is 23°C. The vapour pressure of water at this temperature is 0.0278 atm.What was the mass (in g) of the hydrogen peroxide that decomposed?
