Answer to Question #98628 in General Chemistry for Melanie Petges

Question

A chemist adds 1.25L of a 8.0 * 1o^-5 uM silver(II) oxide solution to a reaction flask. Calculate the mass in micrograms of silver(II) oxide the chemist has added to the flask. Round your answer to 2 significant digits

Answer 1

$Molarity= 8×10^{-5}\mu M$

$Volume =1.25L$

$No of moles = 8×10^{-5}×1.25=10^{-4}\mu moles$

Mass of $AgO=10^{-4}×123.868=0.0123868=0.012\mu g$ (Answer)
