Calculate the number of moles of solute in {eq}46.17 \ mL {/eq} of {eq}0.1315 \ M \ K_2Cr_2O_7(aq). {/eq}

## Question:

Calculate the number of moles of solute in {eq}46.17 \ mL {/eq} of {eq}0.1315 \ M \ K_2Cr_2O_7(aq). {/eq}

## Molarity of a Solution:

Molarity is defined as one type of several common ways of expressing the concentration of a particular solution. Suppose that a particular number of moles of a solute (a substance that is dissolved in a solvent) is defined as {eq}n {/eq} and the total volume of the solution is {eq}V {/eq} in liters, then molarity of the resultant solution {eq}c {/eq} is defined as a ratio of moles to volume, specifically {eq}c = \dfrac{n}{V} {/eq}.

{eq}V = 46.17~mL\\ c = 0.1315~M {/eq}

Using the molarity formula, we have:

{eq}c = \dfrac{n}{V} {/eq}

Rearranging for the moles of...
