The value of the universal gas constant is 0.082 (L atm)/(mol K) or 8.31 J/(mol k) and 1.00 atm = 760 mmHg or 760 torr.

When a sample of H2​​​​O​​​​​​​​​​​​2 is decomposed, 350 mL of O2 gas is collected at 20 °C and at a partial pressure of 695 torr. How many moles of O2 gas were collect

The value of the universal gas constant is 0.082 (L atm)/(mol K) or 8.31 J/(mol k) and 1.00 atm = 760 mmHg or 760 torr.

Use the balanced equation for the reaction to determine how many grams of H2O2 were decomposed in the reaction and how many ml of liquid water would be collected upon cooling (assume a density of water of 1 g/ml)?
