Calculate the mass of silver chloride in grams required to make 5.8 g of silver plating.

Silver chloride is simply AgCl while silver is Ag so we see that there is one mole to one mole correspondence. First calculate the moles of Ag:

moles Ag = 5.8 g / ( 107.87 g/mol)

moles Ag = 0.0538 mol

Then the mass of AgCl required:

mass AgCl = 0.0538 mol * 143.32 g/mol

mass AgCl = 7.71 grams

increased stability in the completion of fluorine's outer shell.

the temperature of the gas, in k, not celsius.
