A chemist prepares a solution of zinc oxalate (ZnC204) by weighing out 3.87 mg of zinc oxalate into a 400. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in giL of the chemist's zinc oxalate solution. Round your answer to 3 significant digits.​

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
