    "If your hydrogen peroxide solution is 100 vol (quite reasonable for a strong stock solution) this means that 1000 cm3 of the H2O2 produces 100,000 cm3 of oxygen.

    100 dm3 of oxygen = 100/24 moles = 4.17 moles

    If 4.17 moles of oxygen are produced then there must have been 4.17 x 2 moles of hydrogen peroxide = 8.34 moles in 1 dm3 = 8.34 molar.

    so if 100 vol is 8.34 molar then 1 vol = 0.0834 molar etc."

    Ohhh I get it, 2 vol is 0.0834 molar x 2 which is = 0.1668 molar! Can you just check Ive done it right, because to be honest im hopeless with calculations, and 1 more thing does 0.1668 molar mean 0.1668 mol dm-3? Thanks for all your help
