You heated 4.442 grams of baking soda in a crucible to produce 3.56 grams of a solid product. The product could be NaOH, Na2CO3, OR Na2O.
What mass of NaOH could have produced? What is the percent error?
What mass of Na2CO3 could have been produced? What is the percent error?
What mass of Na2O could have been produced? What is the percent error?
You used 1.05 grams of solid and it required 17.58 ml of 1.00 M HCl to titrate the endpoint. Determine the number of moles HCl requires in your titration.
Assuming the mole ration between the solid and the HCl is 1;1, determine the molar mass of the solid. Now assume the ratio is 1;2, what is the molar mass of the solid.
