- A volumetric flask made of Pyrex glass is calibrated at 20 °C.It is filled to the 100 mL mark with 35 °C acetone. After the flask is filled the acetone cools and the flask warms so that the combination of acetone and flask reaches a uniform temperature of 32 °C. The combination is then cooled to 20 °C. a) What is the volume of the acetone when it is at 20 °C? b)At the temperature of 32 °C, does the level of acetone lie above or below the 100 mL mark?arrow_forwardThe iodine contained in every one mL of the 0.010 M iodine solution in the buret will react with 1.76 mg of vitamin C. (In other words, every mL of iodine solution needed for the titration indicates the presence of 1.76 mg of vitamin C in the juice sample.) If your titration used 7.11 mL of iodine solution, what mass of vitamin C is in your fruit juice sample (in milligrams, mg)? Include the unit and two decimal places in your answer.arrow_forwardYou wish to quantify your favourite compound in an experimental solution using spectrophotometry. First, you use standard solutions of your favourite compound to collect the following standard curve data. Calculate the slope of the line of best fit to two decimal places, and enter it in the box below the table. Standard curve data Conc (MM) 0.300 0.600 0.900 1.200 1.500 Abs 0.225 0.450 0.675 0.900 1.125 Next, you prepare an experimental sample by mixing 0.25 mL of the compound solution with 9.75 mL of distilled water. Calculate the dilution factor and enter it as a whole number (no decimals). Next, you read an absorbance of 0.72 absorbance units for the diluted sample. Calculate the concentration (mm) of the original solution of the compound. Round this answer to one decimal place. Previous Page Next Page MacBook Air Page 5 of 13arrow_forward
