Recall that question 2 of pre-lab quiz for project 3 introduced that molarity (molar concentration) of a solution is defined as the ratio of the amount of solute in moles to the amount of solution in liters. molarity is a common unit to express solution concentration. m o l a r i t y o f a s o l u t i o n = n u m b e r o f m o l e s o f s o l u t e ( m o l ) v o l u m e o f s o l u t i o n ( l ) during the first week of this project, you need to start with preparing stock solutions for different dyes. suppose you choose to prepare the stock solution of red dye #40 by measuring 0.05 g of dye powder, and making a 100 ml dye solution with volumetric flask. what is the molarity of this stock solution (in mol/l)? (hint: convert mass of dye powder to the number of moles first using molar mass.)
