to find the mass percent of dolomite [CaMg(CO3)2] in a soil sample, a geochemist titrates 13.86 g of soil with 33.56 mL of 0.2516 M HCl. what is the mas percent of dolomite in the soil?
It takes 4 moles HCl to react with 1 mole of dolomite. 0.03356L x 0.2516M 0.008444moles HCl 0.008444moles x 1mole dolomite / 4 moles HCl 0.002111moles dolomite 0.002111moles dolomite x 184.4g/mole 0.3893g part / whole x 100 0.3893g / 13.86g 2.809%
