Dolomite, [CaMg(CO3)2] is found in a soil sample. A geochemist titrates 24.65 g of soil with 57.85 mL of 0.3315M HCl. What is the mass % of dolomite in the soil? ( Write answer to two decimal places, ex. 15.77) Following is the acid/base reaction which occurs during the titration: CO3-2(aq) + HCl(aq) --> HCO3-(aq) + Cl-(aq)
