Answer:
369.4 g.
Explanation:
- The chemical reaction of reacting hydrogen with oxygen to produce water is:
H₂ + 1/2 O₂ → H₂O.
- From the law of conservation of mass states that the mass does not destroyed or created from nothing but it can converted from from to another one.
- The mass of the reactants = the mass of the products
∴ The mass of hydrogen + the mass of oxygen = the mass of water.
∴ The mass of oxygen = the mass of water - the mass of hydrogen = (416.0 g) - (46.6 g) = 369.4 g.
