The answer is B.
About 4. the weight of He is about 4 amus and the weight of O is about 16 amus, so you would need 4 He atoms to get close to the same mass as an O atom. i hope this helps
Answer:
One mole of copper atoms has Avogadro number of copper atoms i.e. 6.022×10
23
atoms.
Given the mass of Copper is 6.4g
Number of Copper atoms in 6.4g =
molar mass
given mass
×Avogadro number
=
63.55
6.4
×6.022×10
23
copper atoms
=6.064×10
22
copper atoms
