The experimental mass is 51.5 grams and the theoretical mass is 50 grams what is the percent error ? Show your work below round your answer to two digits

3%

Explanation:

as error occurred is 1.5(error value) so 1.5 is 3%of 50(original value)

am i too late?

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
