The planet Aragonose (which is made mostly of the mineral aragonite, whose composition is CacOs) has an atmosphere containing methane and carbon dioxide, each at a pressure of 0.10 bar. The oceans are saturated with aragonite and have a concentration of H*equal to 1.8x107 M. Given the following equilibria, calculate the concentration of calcium (in molarity) contained in specific volume of Aragonose seawater: CaCO, (s, aragonite) = Ca+ (aq) + CO (aq) Kp - 6.0 x 10-9 Kco, = 3.4 x 102 CO,(aq) + H,O(I) HCO5 (aq) + H*(aq) K, = 4.5 x 10-7 K2 = 4.7 x 10-1 CO,(g) = CO,(aq) %3D %3D HCO, (ag) = H*(aq) + Co (ag) Don't panic! Assume that pressure of CO2(g) at equilibrium is 0.10 bar. Reverse the first reaction, add all the reactions together, and see what cancels.
