This question requires the mass of sulfuric acid and a balance equation. The complete question is given below
Question:
According to the following reaction, how many grams of water are produced in the complete reaction of 24.1 grams of sulfuric acid?
H₂SO₄(aq) + Zn(OH)₂(s) ---------> ZnSO₄(aq) + 2H₂O(l)
Answer:
8.85 grams of water is obtained from 24.1 grams of sulfuric acid according to the given reaction
Explanation:
In this problem, the mass of water can be determined by using the balanced chemical equation.
Step 1: Write all data
Molar mass of water = 18 g
Molar mass of sulfuric acid = 98 g
Given mass of sulfuric acid = 24.1 g
Mass of water from reaction = ?
Step 2: Write statement for conversion
Given equation shows that
1 mole of H₂SO₄ gives 2 moles of water
Step 3: Convert moles into molar mass
Convert the moles into molar mass so, the statement becomes,
98 g of H₂SO₄ gives (2)(18) g of water
1 g of H₂SO₄ gives (2)(18)/98 g of water
Step 4: Use given data
24.1 g of H₂SO₄ gives (2)(18)(24.1)/98 g of water
amount of water = 8.85 g
