Hydrogen sulfide and concentrated sulfuric acid react to form water and sulfur dioxide as shown in the following reaction:
Law Incorporation [45]

Answer:

2 moles of SO₂

Explanation:

Equation of reaction

H₂S + 3H₂SO₄ → 4H₂O + 4SO₂

From the equation of reaction above,

1 mole of H₂S will produce 4 moles of SO₂

1 mole of H₂S = 4 moles of SO₂

0.5moles of H₂S = zmoles of SO₂

z = (0.5*4) / 1

z = 2 moles of SO₂

0.5 moles of H₂S will produce 2 moles of SO₂

A bottle of wine contains 9.81 grams of C2H5OH, dissolved in 87.5 grams of water. The final volume of the solution is 100.0 mL.
dimulka [17.4K]

Answer:

[EtOH] = 2.2M and Wt% EtOH = 10.1% (w/w)

Explanation:

1. Molarity = moles solute / Volume solution in Liters

=> moles solute = mass solute / formula weight of solute = 9.8g/46g·mol⁻¹ = 0.213mol EtOH

=> volume of solution (assuming density of final solution is 1.0g/ml) ...

volume solution =  9.81gEtOH + 87.5gH₂O = 97.31g solution x 1g/ml = 97.31ml = 0.09731 Liter solution

Concentration (Molarity) = moles/Liters = 0.213mol/0.09731L = 2.2M in EtOH

2. Weight Percent EtOH in solution (assuming density of final solution is 1.0g/ml)

From part 1 => [EtOH] = 2.2M in EtOH = 2.2moles EtOH/1.0L soln

= {(2.2mol)(46g/mol)]/1000g soln] x 100% = 10.1% (w/w) in EtOH.
