900 grams of coal are completely combusted. How many CO2 molecules are produced, and what volume do they occupy measured at 25C. and 1.3 at. of pressure. If the coal contains 2.5% S(sulfur), the same as in combustion becomes sulfur dioxide, which is the volume of sulfur dioxide emitted under normal conditions.

900 grams of coal are completely combusted. How many CO2 molecules are produced, and what volume do they occupy measured at 25C. and 1.3 atmospheres of pressure. If the coal contains 2.5% S, the same as in combustion, it becomes sulfur dioxide, what is the volume of sulfur dioxide emitted under normal conditions?

is this your question? , the problem is like this, I don't understand what you need?

" If the coal contains 2.5% S "
