Question

the number of moles in 12.046 x 10^23 atoms of copper
​

Answer 1

Explanation:

No of atoms =moles*6*10power 23

so,12.046*10power23/6*10power23

=2 moles.

hope it helps u..

Answer 2

We know,

• 1 Mole = 6.023 × 10²³ particles

Given,

• Number atoms of copper = 12.046 × 10²³

Now,

$\rm{ \green{Number \: of \: moles}} = \dfrac{ \textsf{ \purple{Total Number of atoms}}}{ \textsf{ \purple{Atoms in one mole}}}$

Therefore,

• Number of Moles in 12.046 × 10²³ atoms of copper = (12.046 × 10²³) ÷ (6.023 × 10²³)

$\implies \bf \dfrac{12.046 \times {10}^{23} }{6.023 \times {10}^{23} } \\ \\ \tt \to \dfrac{12.046}{6.023} \times \cancel{ \dfrac{ {10}^{23} }{ {10}^{23} } } \: \: \to \red2$

Hence,

• There are 2 Moles in 12.046 × 10²³ atoms of Copper.
