Ap bio question? im sooooo confused?

Question

A dialysis bag has an intial mass of 26.3 g and a final mass of 30.2 g. Find the % change in mass?

thank u all soooooooo much

Answer 1

No. It's 30.2g-26.3g. That is 3.9g, which is what percent of the original 26.3 g? That would be your answer. Can you do the math?

Answer 2

30,2 g - 26,3 g  = 3,9 g increase

The initial mass was 26,3 g.

The  % increase is thus   3,9 / 26,3  x 100 = 14,83% increase

Answer 3

its like 30.2-26.3

divide that by 100

Answer 4
