An atom of gold has a mass of 3.25x10^-22.What is the mass of 8000 atoms?Express in scientific notation.

Answer 1

3.25e-22 * 8000 = 2.6e-18 = 2.6*10^-18

e = to the power of.

Answer 2

e = ten to the power of, rather.

Answer 3

1000 = 10 ^ 3

8000 = 8 * 10 ^ 3

3.25 * 10 ^ - 22 * 8 * 10 ^ 3 =

3.25 * 8 * 10 ^ - 22 * 10 ^ 3 =

26 * 10 ^ - 22 * 10 ^ 3 =

26 * 10 ^ ( - 22 + 3 ) =

26 * 10 ^ ( - 19 ) =

2.6 * 10 * 10 ^ ( - 19 ) =

2.6 * 10 ^ 1 * 10 ^ ( - 19 ) =

2.6 * 10 ^ ( - 19 + 1 ) =

2.6 * 10 ^ - 18
