Good technique would collect hydrogen by gas displacement (eg pushing water from an upturned measuring cylinder) which would give a reliable idea of the volume of hydrogen, a far better way of measuring the amount than estimating the approximate density. | |

Good practice is starting with symbolic algebraic expressions and keeping it this way until all is ready to plug in literal numbers. It helps in focusing on principles, mistakes are easier to spot, orientation is improved, Q/A is reusable and has bigger permanent value. You may find useful formatting mathematical/chemical expressions/formulas. | |
