If 5.00g iron (III) chloride hexahydrate is completely dehydrated,how w many grams of anhydrous iron (III) chloride will remain?

Melissa is attempting to synthesize some potassium ferrioxalate and calculates that her theoretical yield should be 9.65 g. When she runs her experiment, crystallizes out the iron (II) oxalate dihydrate and dries it, she obtains an experimental yield of 7.98 g. What was the percent yield for her experiment?

One of the hydrates of CoSO4 is cobalt(II) sulfate hexahydrate . A 71.1 gram sample of CoSO4 6 H2O was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, how many grams of the anhydrous compound remained?

26) (CH2CI2). Consider the following two-step preparation of dichloromethane (step 1) CH4 Cl2 CH;CI HCI + (step 2) CH;CI Cl2 CH2CI2 HCI If each reaction, carried out in the presence of excess Cl2, gives a 90% yield of products, what is the maximum number of grams of dichloromethane that can be produced from 9.5 g of CH4. Show your calculations. Answer:
