5-8. A method of analysis yields masses of gold that are low by 0.4 mg. Calculate the percent relative error caused by this result if the mass of gold in the sample is *(a) 500 mg. *(c) 150 mg. 5-9. The method described in Problem 5-8 is to be used for the analysis of ores that assay about 1.2% gold. What minimum sample mass should be taken if the relative error resulting from a 0.4-mg loss is not to exceed *(a) -0.1%? (b) 250 mg. (d) 70 mg. (b) -0.4%? *(C) -0 8%? -1 1%?
