2M
Explanation:
Given that:
V1 = 50mL
M1 = 40M
V2 = 1000mL
unknown:
M2 = ?
Solution:
Concentration is the number of moles solute in a solution.
Since the number of moles in the solute remains the same;
Concentration = 
number of moles = concentration x volume
Number of moles before and after the dilution remains the same;
M1 x V1 = M2 x V2
M1 is initial concentration
V1 is initial volume
M2 is final concentration
V2 is final volume
40 x 50 = M2 x 1000
M2 = 2M

<em>Answer:</em>
- Pivalic acid forms a strong conjugate base.
<em>Explanation:</em>
- Strong acid has weak conjugate base
- Weak acid has strong conjugate base
As in this case, pivalic acid is weak acid (Due to electron donating effect of <em>tert.</em> butyl group) having pka value of 5.0 , so its conjugate base will be strong as compare to formic acid which is stronger acid.
<em>Summary: </em>
- As pivalic acid is weak acid as compare to formic acid, so its conjugate base will be strong and vice versa.
