To get mL from mass just devide 1000g with 10.5 to get 95.23mL
160.0g
Mass =volume x density = 200.0 mL x 0.8 g/mL= 160.0 g
Answer:
The atomic weight of an element represents the ratio of the average mass of atoms of a chemical element.

Answer: <em>
pH=2.25 </em></h3>
Explanation:
monochloroacetic acid also means: chloroacetic acid
pKa of monochloroacetic acid= 1.4 x 10^-3 (I believe this should have been given in the problem or perhaps in the textbook)
Formula: pH= pKa + log ( some number in M)
pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25
pH= 2.25
