a formula calls for 10.000 grams of Na2SO4.3H2O(f.w. 196.050) to be weighed out and added to a meatloaf sauce. All you have in your laboratory is anhydrous Na2SO4 (f.w. 142.050). how many grams of anhydrous Na2SO4 must be weighed out?
Homework Answers
Moles of Na2SO4.3H2O = moles of Na2SO4
mass / molar mass of Na2SO4.3H2O = mass of Na2SO4 / molar mass of Na2SO4
10 / 196.05 = m / 142.05
Solving, m = 7.25 g

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...
