| July 22, 2021 | education
The combustion reaction of hydrogen is described by the following chemical reaction equation:
2H2 + O2 = 2H2O;
From one mole of oxygen, two moles of water are formed.
Find the mass 3 x 2 = 6 moles of water.
Its molar mass is:
M H2O = 2 + 16 = 18 grams / mol;
m H2O = 6 x 18 = 108 grams;
