1 mole ------------- 6.02 x 10²³ atoms
0.70 moles -------- ( atoms platinum )
atoms platinum = 0.70 x ( 6.02 x 10²³ ) / 1
= 4.2 x 10²³ atoms platinum
hope this helps!
Answer:
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
