For each of the dyes you will carry out the following dilution scheme: Dilution #1 = 2.50 mL of stock + 22.50 mL water Dilution #2 = 15.00 mL of #1 + 10.00 mL water Dilution #3 = 17.50 mL of #2 + 7.50 mL water Dilution #4 = 15.00 mL of #3 + 10.00 mL water Determine the concentrations of the stock solutions and the four dilutions and enter them into the tables below. Pay attention to the number of significant figures for each calculation and be sure to enter your answer to the correct number of significant figures. Not all answers will have the same number of significant figures.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
