Acidified water is electrolysed for 1.00 hour at a steady current of 0.600 A. The volume of oxygen produced at STP (22.4 L mol $^{- 1}$ ), in mL (nearest integer), is.

Numerical answer type, answer in mL, tolerance 1.

Answer: 125 mL

Q = 0.600 \times 3600 = 2160 C

, moles of electrons

= 2160/96500 = 0.02238

2 H X_{2} O O X_{2} + 4 H X^{+} + 4 e X^{-}

: moles

O X_{2} = 0.02238/4 = 5.596 \times 1 0^{- 3}

. Volume

= 5.596 \times 1 0^{- 3} \times 22400 = 125.4 \approx 125 mL
