Question

Which has more atoms,50g of cu or 50g of iron?

Answer 1

$\textbf{\huge{\underline{ Hello Mate! }}}$

Atomic mass of Cu ( copper ) = 63.5g

No. of moles = (W g) / (W g/mol)

= 50 g / 63.5 g/mol

= 0.787 mol

1 mole of Cu = 6.022 × $10^{23}$ atoms.

0.787 mole of Cu = 6.022 × $10^{23}$ × 0.787 atoms

= 4.74 × $10^{23}$ atoms.

Atomic mass of iron = 56 g/mol

No. of moles = 50 g / 56 g/mol

= 0.893 mole

1 mole of Fe = 6.022 × $10^{23}$ atoms.

0.893 moles = 0.893 × 6.022 × $10^{23}$ atoms.

= 5.34 × $10^{23}$ atoms.

On comparing we get,

$\textsf{\red{ 50g of Fe will have more atoms }}$

$\textbf{ Have great future ahead! }$
