What is the concentration of K+ ions in a 0.045 M K2CO3 solution assuming complete dissociation?
When you are given a concentration for a compound, such as 1 M NaCl, it indicates the number of moles of formula units per liter (formula-unit concentration). By multiplying the formula-unit concentration by the number of ions per formula unit, you arrive at the ion concentration. For example, a 1 M solution of NaCl has a 2 M ion concentration (1 M of Na+ ions and 1 M of Cl− ions) because there are two ions per formula unit of...
