Determine the absolute error and relative error in ppm CaCO3 associated with a single standardization and titration of an unknown CaCO3 solution

_ppm CaCO3= (0.5000g x 1.0011purityx0.02500L x 0.02823Lx 1000mg) / (0.500L x 0.02743x 0.05000Lx1g)

where..

1000mg/1g is the conversion factor for ppm

0.5000g is the weight of CaCO3 in the primary standard

1.0011 is the purity of the CaC)3

0.02500L is the pipette volume of the standard CaCO3 solution

0.02823L is the buret volume of the EDTA

0.500L is the volumetric volume of the original primary standard CaCO3 solution

0.02743L is the buret volume of EDTA used to titrate the 0.02500L sample of the standard CaCO3 solution

0.05000L is the pipette volume of the unknown CaCO3 solution
