.20 M NaOH is the Molarity
Part 1 Data is .20 M NaOH
Homework Answers
Hi my apologies to say that part b & part c requires additional data points A, B, C, and D from part "a". Hence i am gonna answer part a at this moment.
NaOH + HCl ==> NaCl + H2O
1 mol NaOH reacts with 1 mol HCl
M1V1 = M2V2 formula we can use here
M1 = 0.100 M HCl, V1 = 20.00 mL
M2 = 0.20 M NaOH, V2 = to be find out
V2 = (M1V1 / M2) = (0.100 M x 20.00 mL) / 0.20 M = 10 mL
Answer: Volume of NaOH needed to reach the equivalence point = 10.00 mL
Hope this helped you!
