Aluminum to hydrogen gas ratio is 2 : 3 by looking at the coefficients of aluminum on the reactant side and hydrogen gas on the product side.
So from 2.0 mol of Al, 3.0 mol of H2 would form.
Answer:
0.5133805136 moles.
Explanation:
1 gram of Al2(Co3)3 equals 0.0017112683785004 moles, we need the amount of moles produced in 300 grams of Al2(CO3)3, so we have to multiply 1 gram of Al2(CO3)3 times 300: 0.0017112683785004 x 300, in conclusion,
300 grams of Al2(Co3)3 equals 0.5133805136.
