Answer» ANSWER: EXPLANATION: by POAC of ag 2moles of ag2a = MOLES of ag 2(0.701 / 216+a ) = 0.497 / 108 1.402 / 216+a = 0.497/108 1402 / 216+a = 497 / 108 216+a = 304.66 a=88.66

Answer»

by POAC of ag

2moles of ag2a = MOLES of ag

2(0.701 / 216+a ) = 0.497 / 108

1.402 / 216+a = 0.497/108

1402 / 216+a = 497 / 108

216+a = 304.66

a=88.66
