Volcanoes emit much hydrogen sulfide gas, H2S, which reacts with the oxygen in the air to form water and sulfur dioxide, SO2. Every 69 tons of H2S reacts with 97 tons of oxygen and forms 37 tons of water. How many tons of SO2 are formed

To solve this problem, we can use a ratio based on the given information. We know that for every 69 tons of H2S, 97 tons of oxygen are used to form 37 tons of water and an unknown amount of SO2.

Let's set up a proportion to find the amount of SO2 formed:

69 tons of H2S / 97 tons of oxygen = X tons of SO2 / 37 tons of water

To find X, we cross-multiply the ratio:

69 tons of H2S * 37 tons of water = 97 tons of oxygen * X tons of SO2

We now have:

2553 tons of H2S * tons of water = 97 tons of oxygen * X tons of SO2

Divide both sides of the equation by 97 tons of oxygen:

(2553 tons of H2S * 37 tons of water) / 97 tons of oxygen = X tons of SO2

Now, calculate the value:

X = (2553 tons of H2S * 37 tons of water) / 97 tons of oxygen

X ≈ 980.17

Therefore, approximately 980.17 tons of SO2 are formed.
