hello
i need help with two chemistry questions, i have the answers, i just need the working
thanks everyone
1. a chemist determined the salt content of a sausage roll by precipitating chloride ions as silver chloride. if an 8.45g sample of sausage roll yielded 0.636g of precipitate, calculate the percentage of salt in the food. assume that all the chloride is present as sodium chloride.
answer: 3.07%
2. an impure sample of iron(II) sulphate, weighing 1.545g, was treated to produce a precipitate of Fe2O3. if the mass of the dried precipitate was 0.315g, calculate the percentage of iron in the sample.
answer: 14.3%
PLEASE HELP ME FIGURE THESE OUT!!
thanks again
