What is the mass of silver metal produced from 6.35 g of copper? __cu (s) + __agno3 (aq) → __cu (no3) 2 (aq) + __ag (s) ?

The mass of silver metal produced from 6.35g of copper is 21.574 grams

calculation

Cu + 2AgNO3 → Cu (NO3) 2 + 2 Ag

find the moles of Cu used = mass/molar mass of Cu

moles = 6.35/63.5 = 0.1 Moles

by use of mole ratio between Cu to Ag which is 1:2 the moles of Ag is therefore = 0.1 x2 = 0.2 moles

mass of Ag = moles x molar mass

= 0.2 moles x 107.87 g/mol = 21.574 grams
