How can we express the mass of an aluminum atom in scientific notation?

a. 4.48 x 10^22 g
b. 4.48 x 10^-24 g
c. 4.48 x 10^-22 g
d. 4.48 x 10^23 g
e. 4.48 x 10^-23 g

Answer:

The correct way to express the mass of an aluminum atom in scientific notation is 4.48 x 10^-23 g, corresponding to choice (e).

Atoms are the building blocks of matter, and understanding them opens up a whole new world of possibilities in the field of science. When it comes to expressing the mass of atoms, particularly small ones like aluminum atoms, scientific notation is the way to go.

In this case, the mass of an aluminum atom is given as 0.000 000 000 000 000 000 000 0448 grams. To express this in scientific notation, we need to move the decimal point to create a number between 1 and 10 multiplied by a power of 10.

After moving the decimal point 23 places to the right, we arrive at the scientific notation of 4.48 x 10^-23 g. This means that the mass of an aluminum atom can be represented as 4.48 multiplied by 10 raised to the power of -23 grams.

By correctly expressing the mass of an aluminum atom in scientific notation, we can better understand and work with incredibly small quantities in the fascinating world of atoms.
