Answer: Option (a) is the correct answer.
Explanation:
Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.
For example, in
the subscripts present in it are 7, 7, 1, and 2.
A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.
Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
Answer: 0.011 moles.
Explanation:-
To calculate the moles, we use the equation:

Given :
Mass of copper = 0.71 g
Molar mass of copper = 63.5 g/mol
Putting i the values, we get:

Thus the number of moles of copper in 0.71 g of copper is 0.011 moles.
