To mimic physiological conditions in the laboratory, a phosphate buffer solution is often used. It consists of a mixture of NaH₂PO4 and Na₂HPO4 to create a 10mM phosphate buffer at pH 7.4. How many grams of each must be dissolved in 1000.0mL of water to create such a buffer? (pK₂ of NaH₂PO4 is 7.1)
