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
Weight is properly defined as how much gravity acts upon an object.
I hope this helps!
Answer: The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.
