you are carrying out an experiment to determine the mw of a solid acid with the generic formula h3a. you weigh out 0.630 g of the solid acid in a weigh boat and transfer it to a 125 ml erlenmeyer flask. after dissolving the acid in 25 ml of distilled water, you add 15.44 ml of 0.335 m sr(oh)2 (aq) solution with a buret until your indicator changes color at the equivalence point. what is the mw of the solid acid in units of g/mole?

Respuesta :

The molecular weight of the solid acid in units of g/mole is 25 g/mol

given that :

mass of the solid acid =0.630 g

volume = 40.4 mL = 0.04 L

moles =  molarity × volumes in liter

moles = 0.630 × 0.04 L

          = 0.0252 mol

the molar mass formula is given as:

molar mass = mass / moles

molar mass = 0.630 g / 0.0252 mol

molar mass = 25 g/mol

Thus, carrying out an experiment to determine the mw of a solid acid with the generic formula H₃A. you weigh out 0.630 g of the solid acid in a weigh boat and transfer it to a 125 ml Erlenmeyer flask. after dissolving the acid in 25 ml of distilled water, you add 15.44 ml of 0.335 m Sr(OH)₂(aq) solution . the molecular weight of the solid acid in units of g/mole is 25 g/mol.
