What mass of sulfuric acid can be obtained from 1.8 kg of sulfur oxide (6) if the yield of sulfuric

What mass of sulfuric acid can be obtained from 1.8 kg of sulfur oxide (6) if the yield of sulfuric acid is 90% of the theoretically possible.

Let’s implement the solution:
1. According to the condition of the problem, we compose the equation:
m = 1.8 kg; X g -? W = 90%
SO3 + H2O = H2SO4 – compounds, sulfuric acid was obtained;
2. Calculations by formulas:
M (SO3) = 80 g / mol;
M (H2SO4) = 98 g / mol;
m (SO3) = 1800 g.
3. Determine the amount of sulfur oxide, if the mass is known:
Y (SO3) = m / M = 1800/80 = 22.5 mol;
Y (H2SO4) = 22.5 mol since the amount of substances according to the equation is 1 mol.
4. Find the mass of the product:
m (H2SO4) = Y * M = 22.5 * 98 = 2205 g;
m (practical) = 0.90 * 2205 = 1984.5 g. = 1 kg. 985 BC
Answer: sulfuric acid weighing 1 kg was obtained. 985 BC
