In water hydrogen to oxygen mass ratio is
Web23 okt. 2015 · 2H2 (g] +O2 (g] → 2H2O(l] Notice that you have a 2:1 mole ratio between hydrogen gas and oxygen gas. This means that, regardless of how many moles of oxygen gas you have, the reaction needs twice as many moles of hydrogen gas in order to proceed. You know that you start with 10.0 g of hydrogen gas nad 15.0 g of oxygen. WebHydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas? SOLUTION: 1 g of hydrogen reacts with = 8 g of oxygen ∴ 3 g …
