Scientists write very large and very small numbers using scientific notation. A gram of carbon has about 50,000,000,000,000,000,000 atoms. Express this in scientific notation.
a. Move the decimal until one nonzero digit remains on the left: 5.0000000000000000000
b. Count how the places you moved. In this case, 19 places left.
c. Show that number as a power of 10. The exponent is negative if the decimal moves right and positive if it moves left. Answer: 5 × 10 19
d. Reverse the process to change scientific notation back to a whole number.
