Calculate the concentrationof sodium in the original sample in %w/v. The sample was composed of a mixture of sodiumlactate and sodium carbonate in equimolar amounts. Calculate the amount of sodiumlactate and sodium carbonate in mg/10 ml of the sample (Na = 23, lactate = 89, carbonate =60)

00 P and Hei 3. Considering the techniques and instrumentation used to perform these experiments, identify 2 potential sources of error if you were to repeat this experiment in the "real world". Human error is not an acceptable answer. Discuss at least two possible sources of error that could contribute to your percent error. 4. A student is performing Reaction 2 and does not completely dissolve the NaOH pellets before acquiring the final temperature. How will this affect his value for AH, and his percent error calculations?

Based on the dissolved solute's properties, we can quantify that solute's concentration are too high to permit an accurate measurement. For example, a spectrophotometer can measure the amount of light that passes through a sample solution for If the solute's concentration is too high, a relatively small amount of incident light having the wavelength that corresponds to the solute's absorption behavior will less light is absorbed, and the detector in the spectrophotometer can generate more reliable data. reach the dete ctor, which results in an inaccurate measurement (consider the result if you blocked the light with an opaque…
