Experiment 1- Post-Lab - Manual Quest previous | 4 of 4 I return to assignment For the density matching experiment, imagine that you spilled a bit of one thiosulfate solution sample during the meas an appropriate correction to your mass measurement and recalculate your observed densily In this case, the experimental error underestimates the mass of thiosulfate Does this error result in an over or underestimate of your observed density? urement. As a result your average mass of the th i iosulfate solution was actually 27.5 mg too low Apply I soluion Hints O Undere O Nat enough information i provided O Overestimate O This has no effect on the calculated value of density Submit My Answers Give Up Part B We recorded the temperature of the thiosulfate solution before carrying out the density matching experiment but did not use this information in our calculations However, the density of thiosulfate solutions does exhibit a strong temperature dependence with densily decreasing with increasing temperature If you repealed the experiment at a temperature of 10 0 C higher than you did today, how would your densily measurements change? In general, temperature changes effect the density of liquids more significantly than solids Assume in this case that the temperature change of 10 0°C has a significant (measureable) effect on the densily of the thiosulfate solution but has an insignifcant (not-measureable) on the densiy of the acrylic slug + Hints O Density value would be higher ® Density value would be lower There would be no effect on the measured density value Not enough information is provided 229 AM

Explanation / Answer

Part A:

right answer: not enough information is provided

density = mass / volume. all the informations are here given about mass but not about any volume of the sample. It is not possible to calculate the density with out knowing any volume corrections.

Part B:

density will be lower.

for thiosulfate solution with increasing temperature, the density of the soluetion is decreasing.
