Calcite Dissolution Kinetics | Aquatic Geochemistry

First, it has been understood for many years that the kinetics of calcite dissolution are complex, and that the value of "rate constants" depends on the origin and nature of the mineral, e.g., precipitated powder versus Iceland spar crystal rates (Rickard and Sjöberg 1983; Morse and Arvidson 2002).Although we are as yet unable to easily resolve the …

CaCO3(CAlCITe) molar mass

Example: calculating molar mass. Let's calculate the molar mass of carbon dioxide (CO 2): Carbon (C) has an atomic mass of about 12.01 amu. Oxygen (O) has an atomic mass of about 16.00 amu. CO 2 has one carbon atom and two oxygen atoms. The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol. Lesson on computing molar mass

CAlCITe molar mass

Computing molar mass step by step; First, compute the number of each atom in CAlCITe: C: 2, Al: 1, I: 1, Te: 1. Then, lookup atomic weights for each element in periodic table: C: 12.0107, Al: 26.9815386, I: 126.90447, Te: 127.6 Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (CAlCITe) = ∑ Count i * Weight i =
