What did you include in your question? Check all that apply.
If Beaker #2 is a 1% solution of Y, and Beaker #3 is 1/100th of that in the final solution, what percentage solution would Beaker #3 be?
The independent variable, the one that is intentionally manipulated, is .
Does taking 1 mL of solution Y (pure bleach) out of the first beaker change the solution’s concentration?
How would you best describe the red or pink solutions labeled “2-4”?
