hey, how do i solve this? One gold atom is 3.3 * 10^(-22)g How many atoms do i need to make it weight 1 gram?

You will need =1 / [3.3 x 10^-22] =3,030,303,030,303,030,303,030=3.03 x 10^21 atoms of gold.
Think about this .......
If one atom weighs 1/2 of a gram, we just need to invert the fraction to find out how many attoms in a whole gram = 2/ 1 = 2
So
3.3 x 10-22 =
3.3 / 1022 invert this and we have
1022/ 3.3 ≈ 3,030,303,030,303,030,303,030 atoms
