The answer is on the periodic table. Silver's element sign is Ag and gold's element sign is Au. The molar mass (number under the element sign) is the mass of one mole of that element.

one mole of gold will weigh more

OpenStudy (anonymous):

look at the periodic table, Fe mass 55.845, Ag 107.8682, so Ag weighs more

OpenStudy (joannablackwelder):

@zoomiemoo is correct. We are comparing silver (Ag) and gold (Au), and when we convert to masses of each (using molar mass) we find that the gold weighs more.

OpenStudy (anonymous):

Fe stands for iron @n648c788

OpenStudy (melodious):

A mole of silver atoms is 6.022x1023 silver atoms and a mole of gold atoms is 6.022x1023 gold atoms. Gold is also a heavier element so gold has a greater mass than silver.
