.
Avogadro's number
Explanation:
Silver has a molar mass of
107.87
g
−
1
What does this mean? It means that if I have such a mass of silver, there are Avogadro's number,
6.022
10
23
,
individual silver atoms.
So all I have to do is divide the mass by the molar mass, and multiply this number (a molar quantity!) by Avogadro's number.
So, moles of silver
1.45
And
number of silver atoms
silver atoms
?
srry i can't answer that
Answer:Option (3) less than the sum of its components' masses
true.
Hope this helps!
Option C )The number of atoms of each element is the same on each side of the equation.
