According to that total consumed <strong>water</strong> was 0,167g/min total H2 <strong>production</strong> was<br />

0.018g/min and total O2 <strong>production</strong> was 0.145g/min. Conservation of mass was validated<br />

within a 2% error for the system.<br />

Net mass flow must be zero to say that there is no accumulation or leakage.<br />

Though, it was calculated that there was a little amount of positive net flow on electrolyzer.<br />

This might be due to experimental measurement errors such as chronometer timing on<br />

oxygen output or reading of volume <strong>from</strong> the graduated cylinder.<br />
