How much does 1 pound of gold weigh compared to 1 pound of silver??

They weigh the same.

well since you are comparing lb to lb l am going to state the obvious that they weigh the same. but if you are asking if a pile of silver that weighs a lb will be bigger or smaller than a pile of gold..

Silvers atomic # is 47 with an atomic weight of 107.868 while golds info is
atomic # is 79 with an atomic weight of 196.9665

so looks to me like the answer is gold is heavier.

Must be a product of public education. 1 lb is 1 lb.

Gold is not heavier than silver, but it is DENSER.

Both gold and silver are sold as troy ounces or troy pounds so therefore a pound of gold equals a pound of silver.

However, butter is sold as avoirdupois ounces or avoirdupois pounds so an ounce of butter weighs less than an ounce of gold or silver but a pound of butter weighs more than a pound of gold or silver.
