Assume that magnesium would act atom-for-atom the same as copper in this experiment. how many grams of magnesium would have been used in the reaction if one gram of silver were produced? the atomic mass of magnesium is 24.31 g/mol.

0.1127 grams of Mg is used to produce one gram of silver

Explanation:

Write a balanced equation

Mg(s) +2Ag + (aq) --> (aq) + 2Ag(s)

The atomic mass of magnesium is 24.31 g/mol and the atomic mass of silver is 107.84g/mol

1 g Ag of silver is produced from [(1 mol Mg)(24.31 g/mol)] /[ (2mol Ag)(107.84g/mol)]

1 g Ag of silver is produced from 0.1127 grams of Mg

0.1127 grams of Mg is used to produce one gram of silver

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
