Question

Use the atomic masses to calculate the # of moles of the element present.....
115 mg of silver

Answer 1

This question relates back to the one I previously answered for you. The difference is to convert the 115 mg of silver into g of silver since the atomic mass is in g/mole, you do the same knowing the atomic mass of silver to be 107.87. Does this help answer your question?

Answer 2

but this one is mg now instead of g

Answer 3

That is true, if you know how many mg is 1 g you can do a conversion.

Answer 4

ok thanks
