Question

how many moles of CH4 are contained in 2.408 X10^25 atoms of ch4?
Pls koi bana do pls... Chemistry walon se nhi bana

Answer 1

Answer:

Step-by-step explanation:

mole= given no. of particles/avogadro no.

mole=2.408×10^25/6.022×10^23

mole=39.9867153769

Hope this will be helpful to you and please mark my answer as the brainleast answer.plz plz

Answer 2

The number of moles in 2.408×1023 atoms of methane is 39.9800763739

Given,

$2.408\times {10}^{25}$atoms of methane.

To find,

The number of moles contained in the given number of atoms.

Solution,

The given compound is methane. Any different formula is not there to find the number of atoms in a given number of moles.

The question can simply be solved by the unitary method. There is

$6.023 \times {10}^{23}$

atoms in one mole. So, there must be

$\frac{1}{6.023 \times {10}^{23} }$

moles in one atom. To find the number of moles in any number of atoms, we have to multiply the number of atoms by this number of moles.

So, the number of moles in the given number of atoms is

$\frac{2.408 \times {10}^{25} }{6.023 \times {10}^{23} }$

So, the number of moles is 39.9800763739.
