A chemistry graduate student is given 450. mL of a 1.40M nitrous acid (HNO,) solution. Nitrous acid is a weak acid with K=4.5 × 10 What mass of NaNO, should the student dissolve in the HNO, solution to turn it into a buffer with pH =3.61? You may assume that the volume of the solution doesn't change when the NaNO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.
