A student calibrated a eudiometer by first recording the mass of the empty eudiometer followed by filling the eudiometer to the 50.00 mL line with deionized water at 22°C and recorded the mass. The mass of water was 49.012 g. What measured reading from the eudiometer would correspond to a true volume of 47.89mL?

A beverage drink mix sample is prepared by mixing a packet of beverage powder in a gallon (3.78 L) of water. A sample for analysis is prepared by diluting 10.00 mL of this solution in a 50.0 mL volumetric flask. When measured using a colorimeter, this diluted solution has an absorbance of (3.49x10^-1). The calibration curve for the experiment yielded a linear fit of y = 21655x+(4.7850x10^-2) and an R2 value of 0.9911. Determine the molar concentration of food dye in the analyzed sample.
Part C The absorbance of a cationic iron(II) sample solution was measured in a spectrophotometer, but the instrument returned an error because the absorbance was too high. The sample was then diluted by using a pipette to take 100.0 µL of the sample and injecting it into a cuvette already containing 2.00 mL of water (total volume is 2.00 mL + 100.0 µL). The absorbance value of the diluted solution corresponded to a concentration of 8.57x10-6 M. What was the concentration of the original solution? Express the concentration to three significant figures with the appropriate units. • View Available Hint(s) HÀ ? original concentration of Fe2+ Value Units Submit
Julie has been asked to measure the concentration of a sample solution using a spectrophotometer. After a first attempt, she realizes that, to make the measurement, she must first dilute the sample solution. Julie transfers 1.3 mL1.3 mL of the sample to a 250 mL250 mL volumetric flask and fills the rest of the flask with water to the 250 mL250 mL line. She then uses the spectrophotometer to measure the concentration of the dilute solution as 5.5×10−5 M.5.5×10−5 M. What is the concentration of the starting sample solution?
What are the differences between systematic and random errors and how do they effect accuracy and precision? In what circumstances would you use standard addition (versus a normal calibration curve) to determine the amount of an analyte in a sample? A urine sample, containing analyte Z is analysed by the standard addition method where 5 mL of the original sample was mixed with increasing amounts of a Z standard and each solution diluted to a volume of 50 mL prior to analysis. A plot of the final concentration of the standard in each of the 50 mL samples (x axis) versus The measured signal from the analysis of each 50 mL sample (on y axis) produced a straight line with the general equation: y = 44.72x + 4.06 what was the final concentration of Z in the 50 mL standard addition sample? what was the initial concentration of Z in the original urine sample?
