Which of the following is a proper practice in transferring a certain volume of a liquid reagent from its reagent bottle to your own container? * Hold the reagent bottle in such a way that the palm of your hand covers the label of the reagent bottle. Use a clean and dry pipet or a graduated cylinder to measure the right amount of volume you need, then proceed to transfer the liquid to your container. If the reagent bottle comes with a dropper, use the dropper to get the right amount of liquid you need while making sure that after using the dropper, it is then placed directly at the back of the bottle. all choices are correct

Data obtained: Chips # of extractions Chips' weight (g) Fat weight (g) Regular 3 20.043 6.745 3 20.187 6.438 3 20.198 7.451 Low fat 3 19.456 3.982 3 20.072 4.547 3 20.192 4.589 Mass percent is a method of expressing the concentration of a substance in a mixture or element in a compound. It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent. The formula is: mass % of component= (mass of component / total mass) x 100% 1) Reproduce the following table, and use the data to determine the mass % of fat in the chips for each trial. 2) Show one example calculation.

1. Several students performed this experiment without paying adequate attention to the details of the procedure. Briefly explain what effect each of the following procedural hanges would have on the size of the volume- to- temperature ratio calculated by the students. (a) One student failed to replenish the boiling water in the boiling- water bath as the flask was being heated. At the end of the 6 min of heating, the boiling water in the bath was only in contact with the lower portion of the flask. (b) Following the proper heating of the flask in the boiling water, a student removed the flask from the boiling- water bath but only partially immersed the flask in the ice-water bath during the cooling period. (c) A student neglected to close the pinch clamp before removing the flask from the boiling water bath and immersing it in the ice-water bath. (d) One student neglected to measure the volume of the flask before leaving the laboratory. Because the procedure called for a 125-mL…

In lab, you add 1.985 g salicylic acid to a 125 mL Erlenmeyer flask, as listed in the procedure. You carefully add 4.0 mL acetic anhydride, swirl for a few minutes, then have your TA add 5 drops of sulfuric acid. After completing the synthesis and filtering, you place the crystals to dry on an evaporating dish that weights 21.173 g. After drying, the crystals and evaporating dish weigh 23.472. Calculate the percent yield of aspirin. Insert the value as a percentage, but without the percent sign.
