The required Standard electrode potential is +1.18V.
What is Standard electrode potential?
- The difference in voltage between the cathode and anode is known as the standard cell potential. View Cell Potentials for more details. All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
- The difference between the two electrodes, known as the standard cell potential (Eocell), creates the cell's voltage.
- The equilibrium potential can be measured using the standard electrode potential.
- The potential of a cell under normal state circumstances, which are roughly represented by concentrations of 1 mole per litre, is known as the cell's standard state potential.
Given that,
E°cell ,
0.0-(-1.18)=+1.18V
=+1.18V
The required Standard electrode potential is +1.18V.

Answer:
T-shirts and
Baseball Caps
Step-by-step explanation:
GIVEN: The ninth graders at a high school are raising money by selling T-shirts and baseball caps. The number of T-shirts sold was three times the number of caps. The profit they received for each T-shirt sold was , and the profit on each cap was
.
TO FIND: If the students made a total profit of , how many T-shirts and how many caps were sold.
SOLUTION:
Let the total number of T-shirts sold are
Let the total number of Baseball Caps sold are
Profit received on each T-shirt
Profit received on each Baseball Caps
Total profit received on T-shirts
Total profit received on Baseball Caps
Also,
The number of T-shirts sold was three times the number of caps.
putting in equation,
Hence total t-shirts and
baseball Caps were sold.
