The number of bacteria in the dirt sample can be expressed in scientific notation as 8.6 x 10^7.
To find out the number of bacteria in a 19-gram sample, we can set up a proportion:
(8.6 x 10^7 bacteria) / (1 gram) = (x bacteria) / (19 grams)
Solving for x, we can cross-multiply:
8.6 x 10^7 * 19 = x
The result is 1.634 x 10^9 bacteria in a 19-gram sample.
