1.	A copper plate of 20 cm x 10 cm is to be plated with silver of 1 mm thickness on both the sides. Number of moles of silver required for plating is (density of silver =10.8 g m /cc)____________
Answer» SOLUTION :VOLUME = `20xx10xx0.1=20C C` `1C C-10.8g` `20C C-20xx10.8=2169` On both sides `=2xx216=432g` `therefore` No. of moles of `Ag=(432)/(108)=4`
