mass of copper ? please fast

achal751: Answer:

1 atom of Cu has a mass of 1.055×10−22 g.

Explanation:

1 atom Cu⋅1 mol Cu6.022×1023atoms Cu⋅63.546 g Cu1 mol Cu=1.055×10−22g Cu

1 atom of copper must be converted in moles to express it as a quantity that can be converted into grams (our second step).

Avogadro's Number (1 mole=6.022×1023particles)and the relative atomic mass of copper (1 mole of copper = 63.546 g) are the equalities required to make this conversion.
