C. 8.415 × 10^13
To find the number of bacteria in a cubic yard of compost, you need to multiply the number of bacteria in one gram by the number of grams in a cubic yard.
1.1E9 bacteria per gram x 765,000 grams = 8.415 x 10^13 bacteria
Therefore, the scientist would expect to find approximately 8.415 x 10^13 bacteria in a cubic yard of the same compost.
An environmental scientist tested a compost sample in the lab to find the number of bacteria it contained. The following output was given on her machine for one gram of compost.
1.1E9
