Calculate `E_(cell)^(0)` of (at 298K)
`Zn(s)//ZnSO_(4)(aq)||CuSO_(4)(aq)//Cu(s)`
given that `E_(Zn//Zn^(2+)(aq))^(0)=0.76V`
`E_(Cu(s)//Cu^(2+)(aq))^(0)=-0.34V`

Explanation

To calculate the standard cell potential \( E_{cell}^{0} \) for the given electrochemical cell at 298 K, we can follow these steps:

### Step 1: Identify the half-reactions
The cell consists of two half-reactions:
1. **Zinc half-reaction (oxidation)**:
\[ \text{Zn(s)} \rightarrow \text{Zn}^{2+}(aq) + 2e^{-} \]
