Answer: The mass in 
atoms of zinc is 0.405 g.
Explanation:
Given: Atoms of zinc =
It is known that 1 mole of every substance contains 
atoms. So, the number of moles in given number of atoms is as follows.
As moles is the mass of a substance divided by its molar mass. So, mass of zinc (molar mass = 65.39 g/mol) is calculated as follows.
Thus, we can conclude that the mass in atoms of zinc is 0.405 g.
Answer:
0.45 M
Explanation:
Now we need to make use of the dilution formula
C1V1= C2V2
C1= initial molarity of the solution which is the unknown
V1 = initial volume of the solution which is 175 ml
C2 =final molarity of the solution= 0.315 M
V2= final volume of solution= 250 ml
From C1V1= C2V2 we have;
C1= C2V2/V1
C1= 0.315 × 250/ 175
C1= 0.45 M
If it's to balance the equation then it's already balanced.
