Mass of gas produced : 15 g
<h3>Further explanation
</h3>
In general, the reaction takes place in the open air. If the reaction results in the form of gas as in combustion, the mass of the reaction results will be smaller than the original mass.
Conservation of mass applies to a closed system, where the masses before and after the reaction are the same
So In a closed/isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.
Mass of solution A = 70 g
Mass of solution B = 35 g
Mass of mixture : 90 g
Mass of gas : X
Mass of gas X :
FeO·TiO₂
w(Ti)=M(Ti)/M(FeO·TiO₂)
w(Ti)=47.88g/mol/151.73g/mol=0.3156 (31.56%)

Hello, this question is incomplete. The complete question would be:
"Write the balanced chemical equation for the following reaction.
Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water"
Answer:
Fe2O3 + 3 H2 = 2 Fe + 3 H2O
Explanation:
In a chemical reaction, the structure of atoms as chemical elements is unchanged. Atoms in one element do not become atoms in another element. There is also no loss or creation of new atoms. The number of atoms of the reagents must be equal to the number of atoms of the products. When this happens, we say that the chemical equation is balanced.
For this reason, we can state that the balanced chemical reaction where solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water would be:
<em>Fe2O3 + 3 H2 = 2 Fe + 3 H2O
</em>
