A chemist prepares a solution of silver(II) oxide (AgO) by measuring out 0.00339 μmol of silver(II) oxide into a 450. mL volumetric flask and filling the flask to the mark with water.

Question

Calculate the concentration in mmol/L of the chemist's silver(II) oxide solution. Round your answer to 3

 significant digits.

= ____ mmol / L

Answer 1

0.00338 umol / 450 ml x 1000 ml / L = 7.511x10^-3 umol / L x 1 mmol / 10³ umol = 7.51x10^-6 mmol/L
