Answer 1

`8.18 * 10^23 atms` of nickel with significant figures.

Explanation:

Use dimensional analysis and Avogadro's number:
`79.7 * ((1mol)/(58.69g)) *((6.022*10^23 atms)/(1mol))`

Then plug it into a calculator to get the answer:
`8.18 * 10^23 atms` of nickel with significant figures.

***In case you were wondering, 58.69 g is the mass of one mole of Nickel (you can get this from the periodic table).
