Question 213360: A sample of copper with a mass of 63.5g contains 6.02X10^23 atoms. Calculate the mass of a single copper atom.
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! mass of 63.5 g = 6.02x10^23 atoms
.
to find x g = 1 atom ,,,,,,,divide both sides of original eqn by 6,02 x 10^23
.
63.5 g / 6.02x10^23 = 1.0548 x 10^-22 g = 6.02 x10^23/6.02 x 10^23 = 1 atom
.
answer is one atom has mass of 1.0548 x 10^-22 g
