2H2 + O2 → 2H2O
4 → 36
8 → X
X → (8/6) * 36
= 72.0g
What mass of water is produced when 8.0g of hydrogen reacts with excess oxygen? [H = 1, O = 16]
![A compound contains 40.0% carbon, 6.7% hydrogen and 53.3% oxygen. If the molar mass of the compound is 180. Find the molecular formula. [H = 1, C = 12, O = 16]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "A compound contains 40.0% carbon, 6.7% hydrogen and 53.3% oxygen.
