Answer:
The volume of stock solution needed to make the solution is 1875 ml
Explanation:
The parameters given are;
The volume of 75 M solution of H₂SO₄ = 400 ml
The concentration of stock solution = 16.0 M
Number moles per liter of stock solution = 16 moles
Number of moles in required 400 ml solution = 0.4×75 = 30 M
Volume of stock solution that contains 30 M = 30/16×1 = 1.875 l
The volume of stock solution that is required = 1875 ml
Answer:
8 moles SO₂
Explanation:
To find the moles SO₂, you need to multiply the given value by the mole-to-mole ratio. This ratio, between O₂ and SO₂, is made up of the coefficients from the balanced equation.
2 H₂S + 3 O₂ -----> 2 SO₂ + 2 H₂O
12 moles O₂ 2 moles SO₂
-------------------- x ---------------------- = 8 moles SO₂
3 moles O₂
