A marine shellfish must locally maintain to precipitate calcium carbonate CaCO3 under two conditions of equilibrium: a preindustrial atmosphere containing approximately 280ppmCO2 or a modern atmosphere containing approximately 400ppmCO2. Ocean water has pH around 8 . Calculate the concentration of CO2 aq in litermol(M) under the equilibrium condition of a modern atmosphere containing approximately Cair =350ppmCO2. (Round up to 1 digit after the decimal point.) (a) 6.3105M (b) 12.5105M (c) 8.6105M (d) 1.2105M (e) 3.9105M This question is complete and cannot be answered again. Correct answer (d) 1.2105M
