Answer:
C
Explanation:
Let us quickly remember that the EMF of a cell under non standard conditions in given by the Nernst equation.
This equation states that;
E = E°cell - 0.592/n log Q
Where
E = EMF under non standard conditions
E°cell= standard EMF of the cell
n = number of electrons transferred
Q = reaction quotient
If the reaction quotient is greater than 1 then cell potential is less than the standard cell potential.
The cell that generates the lowest cell potential is the cell depicted in option C because Q has the greatest positive value(Q<1).
Answer:
<h3>The answer is 200 cm³</h3>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 150 g
density = 0.75 g/cm³
We have
We have the final answer as
<h3>200 cm³</h3>Hope this helps you
