There are a number of ways to express concentration
of a solution. This includes molarity. Molarity is expressed as the number of
moles of solute per volume of the solution. The concentration of the solution
is calculated as follows:

 

Molarity = 17 g (1 mol / 159.61 g) /
974 mL (1 L / 1000 mL)

Molarity = 0.109 M

Answer : The correct option is, (A) 0.109 M \(CuSO_4\)

Solution : Given,

Mass of \(CuSO_4\) = 17 g

volume of solution = 974 ml

Molar mass of \(CuSO_4\) = 159.609 g/mole

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

\(Molarity=\frac{w\times 1000}{M\times V_s}\)

where,

w = mass of \(CuSO_4\) (solute)

M = molar mass of \(CuSO_4\)

\(V_s\) = volume of solution in liter

Now put all the given values in the above formula, we get the molarity of solution.

\(Molarity=\frac{(17g)\times 1000}{(159.609g/mole)\times (974ml)}=0.109mole/L=0.109M\)

Therefore, the molarity of the solution is, 0.109 M
