Question

Next you convert grams to moles using the molar mass of the starting material in this case coal. I'm going to change the number up slightly so that I don't give away the answers but the final answer we get will be close to the correct answer to the original question. The formula for coal is C135H96O9NS. On anxam that formula will be given to you. Calculate the molar mass from the formula and use the molar mass as a conversion factor between gram of coal and moles of coal. So, how many moles are in 2.6 trillion (2600000000000) grams of coal? Again, write out your answer with all the zeros? 4 pts Question 3 Next, you use the coefficients of the balanced chemical equation to convert from moles of coal to moles of SO2. You'll need to write the balanced equation for the combustion reaction from the formula you used in the previous question. So, if you started with 1.5 billion (1500000000) moles of coal, how many moles of SO2 would be produced? (Again write out all the zeros.)
