If you use a volumetric pipet to transfer 20 mL of a 0.221 M stock solution into a 100 mL volumetric flask and then filled the flask to the calibration mark with
deionized water, what would the concentration (in M) of the new solution be?

In order to prepare .10 M solution of food dye, how many mL of a 1.62 M stock solution should you add to a 100 mL volumetric flask before filling the flask to the calibration mark?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
