Question

At the beginning of an experiment, there are 500 grams of contaminants. Each hour, one fourth of the contaminants

Answer 1

Answer:

0

Step-by-step explanation:

Amount Of Gram= 500

one fourth of gram in one hour=1/4×500 = 125

in four hours the gram filtered out = 4×125= 500

therefore the amount of gram remaining in the contaminants = 500-500= 0 gram
