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.
