Hydrogen 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? |
|
Answer» Solution :HYDROGEN and oxygen combine in the ratio 1:8 by mass to FORM water. Let XG of oxygen gas is required. `"Hydrogen" : "Oxygen" to H_(2)O` 1:8= 3:x `:. (1)/(8)=(3)/(x)` `x = 3 xx 8"":. x = 24 g` `:.` 24 g of oxygen gas would be required to react completely with 3g of hydrogen gas. |
