How many moles of K+ are present in a 343 mL of a 1.27 M solution of K3PO4?


Notice that every mole of this molecule contains 3 moles of the potassium ion K+. Remember this for the end of the problem…

0.343L K3PO4 x 1.27M K3PO4 = 0.43561 moles K3PO4

Now we use that conversion factor from the beginning:

0.43561 moles K3PO4 x (3 moles K+ / 1 mole K3PO4) = 1.308361 moles K+

Round to the correct significant figures:

1.31 moles K+

SOLVED:Calculate the number of moles of each ion – How do I calculate the Normality of an acid or base from its Molarity? There is a relationship between normality and molarity. Normality can only be calculated when we deal with reactions, because Normality is a function of equivalents. Normality refers to compounds that have multiple chemical…How many moles of glycine molecules are contained in 28.35 g of glycine? Solution We can derive the number of moles of a compound from its mass following the same procedure we used for an element in Example 3: The molar mass of glycine is required for this calculation, and it is computed in…Solution concentrations are typically expressed as molarities and can be prepared by dissolving a known mass of solute in a solvent or diluting a stock solution. The molarity (M) is defined as the number of moles of solute present in exactly 1 L of solution.
