What is the mass of a silver coin that contains 1.69x10^23 silver atoms? Report your answer in units of grams

30.27 g

Explanation:

Since the silver is in units of atoms, we have to use Avogadro's number and molar mass.

Avogadro's number: 6.022×10²³ atoms/mol

Molar Mass: 107.87 g/mol

Now that we have everything we need, we can convert atoms to grams.

there all right good

explanation:

c is the answer because when something is left after something evaporates that shows the chemical change.
