Molar gas volume
Chemistry · Secondary 4 · Hard · Molar gas volume
10.0 cm³ of 1.00 mol/dm³ aqueous hydrogen peroxide, H₂O₂, decomposes completely according to the equation:
2H₂O₂(aq) → 2H₂O(l) + O₂(g)
All measurements are made at room temperature and pressure, where 1 mol of gas occupies 24.0 dm³.
What is the maximum volume of oxygen gas that can be produced?
2H₂O₂(aq) → 2H₂O(l) + O₂(g)
All measurements are made at room temperature and pressure, where 1 mol of gas occupies 24.0 dm³.
What is the maximum volume of oxygen gas that can be produced?
- 24.0 cm³
- 60.0 cm³
- 120 cm³
- 240 cm³
