How many atoms of copper in 3. 11 g of copper

son4ous [18]

Atomic weight of copper = 63.5 g
1 mole of copper contains = 63.5g = 6.023 × 10²³ atoms of copper
1 g of copper contains
$= \frac{ 6.023 \times 10²³}{63.5}$ = 9.4 × 10²¹ atoms
Therefore, 3.11g of copper contains
$= 3.11 \times 9.4 \times {10}^{21} \\$
= 29.234 × 10²¹ atoms

Hope you could get an idea from here.
