Explanation:
Answer:
Atoms are neither created, nor distroyed, during any chemical reaction ... Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20). ... Write 'balanced' equation by determining coefficients that provide equal numbers of ...
Explanation:
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!
