Make the equation of the chemical reaction and set the coefficients. How many liters of sulfur dioxide are produced when 12.8 g of crystalline sulfur are burned?

To solve, we write down data on the condition of the problem:

S + O2 = SO2 – compounds, sulfur oxide was formed (4);

Calculations by formulas:
M (S) = 32 g / mol;

M (SO2) = 64 g / mol.

Determine the amount of the original substance:
Y (S) = m / M = 12.8 / 32 = 0.4 mol;

Y (SO2) = 0.4 mol since the amount of substances is 1 mol.

Find the volume of the product:
V (SO2) = 0.4 * 22.4 = 8.96 L

Answer: sulphurous gas with a volume of 8.96 liters was obtained
