Question

Calculate the mass of sodium acetate trihydrate required to make 100. ml of a 0.100 m solution. as part of your preparation for performing this experiment, record your answer to this question in your lab notebook so that you have it ready to use during the lab session. if you do not get this question correct, please make sure to revisit the calculation and check your corrected value with your ta prior to preparing the solution in lab.

Answer 1

Required moles of CH₃COONa.3H₂O = Molarity x Volume of solution in L

                                                            = 0.100 M x (100.0 mL)

                                                            = 0.100 M x 0.100 L

                                                            = 0.01 mol

Required mass of CH₃COONa.3H₂O = Required moles x Molar mass

                                                            = 0.01 mol x (136.08 g / mol)                                                                              = 1.3608 g
