Please show your work, thank you!
1. Express the concentration of 13 ppm of Mg ions in an aqueous solution by mg/L (note: the aqueous solution density: 1.5 g/cm). A. 18.5 mg/L B. 19.5 mg/L C.20.5 mg/L D. 21.5 mg/L 2. A water solution contains 10 mM HCO, and 0.2 mg/L CO We also know the solution pH is 8.5. Calculate the exact alkalinity in mg/L as CaCO,. The exact alkalinity [HCO:1+ ICO HIOH1-IH'1(unit: meq/L) A 200 mg/L as CaCO
