Let, xgrams of oxygen will react with 3g of hydrogen. So, oxygen is 8 times that of hydrogen by mass. Ratio of hydrogen and oxygen in water = 1 : 8 What mass of oxygen gas would be required to react completely with 3g of hydrogen gas? Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. Molar Mass Calculator with steps for Chemistry Problems – determine the molar mass of a compound based on its formula. It shows the law of conservation of mass. Sodium carbonate + ethanoic acid → sodium ethanoate + carbon dioxide + water ![]() Show that these observations are in agreement with the law of co serration of mass. ![]() The products were 2.2g of carbon dioxide. ![]() In a reaction 5.3g of sodium carbonate reacted with 6g of ethanoic acid.
