Answer:
128 grams of sulfur dioxide are produced.
Explanation:
Moles of HCl = 4 moles
According to reaction, 2 moles of HCl gives 1 mole of sulfur dioxide gas.
Then 4 moles of HCl will give:
of sulfur dioxide gas.
Mass of sulfur dioxide gas = 2 mol × 64 g/mol = 128 g
128 grams of sulfur dioxide are produced.
