Answer:
179.2g of O2
Explanation:
Fir, we must obtain a balanced equation for the reaction.
The equation for the reaction is:
2H2 + 02 —> 2H2O
Next, we find the molar mass of H2 and O2 as shown below:
Molar Mass of H2 = 2x1 = 2g/mol
Mass conc. of H2 from the balanced equation = 2 x 2 = 4g
Molar Mass of O2 =16x2 = 32g/mol
From the equation,
4g of H2 required 32g of O2,
Therefore 22.4g of H2 will require = (22.4x32)/4 = 179.2g of O2
