Use the algebraic equation to determine the mass if the volume was 622 mL.  mass (g) = (3.60 g/mL)(volume (mL)) + 11.4 g y= mass (g) m = 3.60 g/mLx= 622 mL b = 11.4 g

please make sure the answer has the correct number of significant digits

I do t understand the explanation given last tine on how to solve once  .08/a = .012/b = .016c   can this be better explainedThis is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

Answer in scientific notation with the appropriate number of significant figures.  For a laboratory experiment, you are provided with a stock solution of food dye. This is the solution from which you will prepare all of your standard solutions. The concentration of the stock solution will be approximately (7.5000x10^-5) mol/L. How many milliliters of this stock solution is needed to prepare 50.0 mL of a (1.50x10^-5) mol/L solution?

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…

I just wanted to know how many sig figs are in the answer below? I think it's 2 but I wanted to be sure Apple Cider Vinegar contains 450mg per tablet. CH₃COOH = 60.06g/mol   Molar mass of Vinegar is (12.01 x 2) + (1.01 x 4) + (16.00 x 2) = 60.06g/mol   450 mg x (10⁻³g/mg) (1 mol/60.06g) x (6.02 x 10²³) = 4.5 x 10²¹ vinegar molecules/tablet.

Please use the corrrect significant digits (3), if needed use scientific notation.
