What mass of K2HPO4 (174.176 g/mol) should be used to make 100. mL of a buffer with a pH of 7.31, assuming the conjugate acid has a concentration of 0.10 M and ignoring activity considerations? (Note that pK2 for phsophoric acid is 7.199, and express your answer with 2 sig figs).

1.75 is the weight of one medium egg

The correct answer is b.hoped i you

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
