Question

A sample of vitamin c is known to contain 2.58 x 1024 oxygen atoms. How many moles of oxygen atoms are present in the sample ? give me full solution​

Answer 1

Answer:

1 mole = 6.022×10²³ atoms

x moles = 2.58×10²⁴ atoms(I think that's what you meant)

now by simple cross multiplication

$x = \frac{2.58 \times {10}^{24} }{6.022 \times {10}^{23} }$

x=0.428 × 10

X=4.28 moles of oxygen atoms is present in the vitamin c

Answer 2

QuésTíon :-

A sample of vitamin c is known to contain 2.58 x 1024 oxygen atoms. How many moles of oxygen atoms are present in the sample ?

Given :-

Moles of oxygen atoms present in the sample ,

Number of oxygen atoms in the given sample is

$\longrightarrow \: 2.58 \times {10}^{24}$

SoluTíon :-

We know that ,

$6.022 \times {10}^{23}$ oxygen atoms = 2 mole

$2.58 \times {10}^{24}$ oxygen atoms

$\longrightarrow \frac{ 2.58 \times {10}^{24} }{6.022 \times {10}^{23} }$

$\longrightarrow 0.428\times 10$

$\red{\sf\longrightarrow \: 4.28 \: mole}$

The AnsWer is 4.28 mole.

Note :-

You have to remember the value of 1 mole .
