    Since the unkown acid is monoprotic, this also equals the number of moles of acid to use. A typical molar mass for an unknown acid in this experiment is 380 g/mol. Using this molar mass, calculate the mass (in grams) of unknown acid you should use per

    A synthesis yielded 222g of phosphoric acid. How many moles of phosphoric acid were produced? I keep dividing 222g/98g (molar mass) which gives me 2.265. Every time I put the answer in, it tells me I am wrong.

    only part of my answer was posted. The real question is: Assuming that the unknown acid sample in question 1 has a mass of 0.177g, what is the molar mass of the unknown? I tried moles = Grams/Molar Mass, but the answer is saying incorrect.
