A 0.210g sample of an acid molar mass=192g/mol is titrated with 30.5mL of 0.108M NaOH to a phenolphthalein end point. Is the acid monoprotic, diprotic, or triprotic?
An experiment requires 42.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
