Question

The weight of 1.5×10 raised to 26 atom of an element is X into 10 raised to -6 KG find the atomic mass of that element

Answer 1

Answer:

To work this out, you need to work out how many moles of silver you have, then multiply that number by Avogadro’s number.

*The atomic weight for silver is 107.87 g/mol

*Avogadro’s number is 6.022 x 10^23.

The calculation is (2.83 g/107.87 g/mol) x (6.022 x 10^23)

This gives 1.58 x 10^22 silver atoms (3 significant figures
