looks like each mole of propanol produces 2 moles of Ag.
If the reaction yields 75%, then each mole of propanol produces 1.5 moles Ag.
So, how many moles of Ag in 5g?
3/2 that of propanol, convert to g.
CH3CH2CHO + 2Ag(NH3)2OH = CH3CH2COONH4+2Ag+H20+3NH3
yield of Ag obtained = 75%
calculate minimum mass of propanal that must have been used to form 5g of silver

still confused
1 mole of Ag = 108 g
So, 5g = 5/108 = 0.0463 moles Ag
Each mole of propanol produces 1.5 moles Ag, so each mole of Ag requires 2/3 moles of propanol (sorry for the 3/2 typo above).
2/3 * .0463 = 0.0309 moles of propanol required.
mol wt of propanol is 58g, so you need 1.79 g
So, 5g = 5/108 = 0.0463 moles Ag

thankyou i appreciate it
thankyou i appreciate it
could u however plz explain how u knew 1 mol of ag =108g
could u however plz explain how u knew 1 mol of ag =108g
never mind i know now thankyou
