3. What is the molarity of a solution containing 5.035 grams of FeCl3 in enough water to make 500 mL of solution? |
|
Answer» tion:Molarity is a term used to define the CONCENTRATION of the SOLUTION. It is defined as the amount of moles of SOLUTE divided by the liters of solutions. Such asMolarity = moles of solute / liters of solution In this case, we need to FIRST find out moles of FECL3 Moles of = mass / molar mass = 5.035/ 162.2 g/mol = 0.031 Thus, molarity = 0.031/ 0.5 = 0.06 M |
