How many grams of potassium carbonate are in 75.0 mL of a 2.44 M solution?

Question:

How many grams of potassium carbonate are in 75.0 mL of a 2.44 M solution?

Molarity

The molarity is defined as the ratio of the moles of solute over the volume of the solution. Note that molarity is directly proportional to the amount of solute present in the solution. This is given by an equation

$$Molarity = \dfrac{moles\ of\ solute}{volume\ of\ solution} $$.

The number of moles can be solved using the equation

{eq}moles = M \cdot (volume) {/eq}.

where,

  • {eq}M = 2.44\ M {/eq} is the molarity of the...
