Calculate the mass of the chalk that contains impurities?
1 Answer
The equation is.....
I get a purity of
Explanation:
We need to work out
Now this quantity
We need
And thus given the 2:1 stoichiometry of the carbonate reaction, there were
i.e. a mass of
And thus
We have assume that the impurities were NOT basic, which would skew the results. Please go over my calculations, and point out any errors or misapprehensions (all care taken but no responsibility admitted!). If there is a step which I have glossed over or ignored, please point it out.
