Chemistry
10.0 g of an unknown acid is titrated to the equivalent point using 65.0 ml of 0.150M KCH. Assuming the acid is monoprotic ( like HCL or HF ) , what is the molecular mass of the acid? Is it possible to find the mols of the acid? (Balanced equation & solution please!)

math
you would take 3/4 and multiply it by six or to make it easyier just take the three and add it six times which is 18 thn you take 18 and divide it by 4 which you cant evenly so take 18/4 and reduce it which is 4 cup and 2/4 or 1/2
