The following question appeared in a recent chemistry exam of mine. I am absolutely positive that I reached the correct answer, but my professor will argue otherwise. Please help confirm my conclusion.
"In order to prepare a standard 1.00 M solution of oxalic acid from H[sub]2[/sub]C[sub]2[/sub]O[sub]4[/sub] * 2H[sub]2[/sub]O (molar mass = 127.07 g/mol), 3.152 g of oxalic acid dihydrate should be dissolved in......"
This was a four-choice question (however, I only remember two--my answer and the professor's).
A) enough water to make 25 mL of solution
B) 25 g of water
I concluded that "A" was the right answer. (I don't want to influence a decision, but we were not given the temp. of the water, nor the density) Any help would be GREATLY appreciated.
