hello guys, i have a question about titration, I get two different answers when i try two different methods of solving. the numbers are the same but the decimals are not, can someone help me please?

the question?

anonymous · Answer

ok, well, i did a lab. The volume of the base was .0255 L and its number of moles were .2. The acid had a volume of .03 L and the number of moles was unknown. For the number of moles aka the concentration, I got .17 when I used 1 method, and 1.7 when I used another method.

"The volume of the base was .0255 L and its number of moles were .2."

are you sure the "0.2" isn't the concentration?  an in "Molarity"?

Assuming that the base only produces 1 $OH^-$ (or abstracts 1 proton) and the acid contributes 1 $H^+$ (i.e. it's monoprotic), then you can use:

$M_{acid}V_{acid}=M_{base}V_{base}$

where V =volume, and M = molarity.
