Answer:
gftyrytyty
Explanation:
According to Avogadro's number, in 1 mole of a substance there are [tex]6.022 \times 10^{23}[/tex] atoms and mass of copper is 63.55 g.
Hence, in [tex]3.50 \times 10^{26}[/tex] atoms the mass of copper will be calculated as follows.
[tex]6.022 \times 10^{23}[/tex] = 63.55 g
Mass in [tex]3.50 \times 10^{26}[/tex] atoms = [tex]\frac{63.55 g}{6.022 \times 10^{23}} \times 3.50 \times 10^{26}[/tex]
= [tex]36.93 \times 10^{3}[/tex]
Thus, we can conclude that mass of copper is [tex]36.93 \times 10^{3}[/tex] for [tex]3.50 \times 10^{26}[/tex] atoms.
