What mass of water is formed by the interaction of 0.5 mol of hydrogen with oxygen?
June 16, 2021 | education
| The combustion reaction of hydrogen is described by the following chemical reaction equation:
2H2 + O2 = 2H2O;
From one mole of hydrogen, one mole of water is formed.
Let’s find the mass of 0.5 mol of water.
Its molar mass is:
M H2O = 2 + 16 = 18 grams / mol;
m H2O = 0.5 x 18 = 9 grams;
