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

8000 * 3.25x10^-22 g = 2.50x10^-18 g

To find the mass of 8000 atoms of gold, we need to first calculate the mass of a single atom and then multiply it by the number of atoms.

Given: Mass of a single gold atom = 3.25 x 10^-22 grams

To express 8000 atoms in scientific notation, we can write it as 8 x 10^3 atoms.

Now, to find the mass of 8000 atoms, we can multiply the mass of a single atom by the number of atoms:

Mass of 8000 atoms = (3.25 x 10^-22 grams/atom) x (8 x 10^3 atoms)

To simplify this calculation, we can multiply the coefficients (3.25 x 8) and add the exponents (-22 + 3):

Mass of 8000 atoms = 26 x 10^-19 grams

Therefore, the mass of 8000 atoms of gold is 2.6 x 10^-18 grams, expressed in scientific notation.
