Answer:
the law of conservation states that energy cannot be created nor destoyed but can be transformed from one state to another.
The <span>henderson-hasselbalck equation is this
pH = pK + log [salt]/[acid]
We are given with
pH = 4.00
</span><span>1.50 l of 0.0200 m solution of benzoic acid
The pK for benzoic acid is
4.20
Solving for the moles of salt,
4 = 4.2 + log 1.5(0.02)/n
n = 71.62 moles
The mass is
m = 71.62 (249.2)
m = 17800 grams</span>
