The result is reasonable and compares well with our rough estimate.
We then substitute the value for molarity that we derived in Example 3. Solution As in previous examples, the definition of molarity is the primary equation used to calculate the quantity sought. To download free model answer for m. Chapter 2 Chemical Equilibrium Answer Key. The solute concentration of a solution may be decreased by adding solvent, a process referred to as dilution. We will compare this ballpark estimate to the calculated result to check for any gross errors in computation for example, such as an improper substitution of the given quantities. Many solutions contain one component, called the solvent, in which other components, called solutes, are dissolved.
