In a simple titration experiment how and why are the results reproducible?

Answer 1

This reminds me of the question of why a teacher counts the children in her class over and over, yet keeps getting the same number. Actually, the reasons are the same.

Answer 2

suppose you wanted to dissolve 106 g of Na2co3 in enough H2O to make 6.00L of solution.
a) what is the molar mass of Na2CO3 ?
b) what is the molarity of this solution ?

Answer 3

Mass Na2CO3 = 106 grams.
moles Na2CO3 in 106 g = 106/106 = 1 mole.

b), M = moles/L = 1/6 = ??

Answer 4
