Geochemists are concerned with the chemistry of natural waters because it affectsdrinking water quality and ecosystem health. A water has the following chemicalanalysis:NatK+Ca2+Mg2+Sr²+Temp120.0 ppm15.00 ppm380.0 ppm22.00 ppm0.8000 ppm25.00°CSO42-CIHCO32-SiO₂pH1115 ppm15.00 ppm150.0 ppm21.0 ppm7.400What are these concentrations in mmol/kg (use excel)?b. Do the charges balance (total positive charges = total negative charges)?c. Would you want to drink this water? Why or why not?
