The given question is asking us to determine how many moles of oxygen are present in 12.044 x 10^23 atoms of oxygen.
To solve this problem, we need to use Avogadro's number, which is defined as the number of atoms or molecules in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23.
Avogadro's Number:
- Avogadro's number is defined as the number of atoms or molecules in one mole of a substance.
- It is approximately 6.022 x 10^23.
Conversion Factor:
- We can use Avogadro's number as a conversion factor to convert between the number of atoms and the number of moles.
- The conversion factor is 1 mole / Avogadro's number.
Calculation:
To find the number of moles of oxygen, we can use the following formula:
Number of moles = Number of atoms / Avogadro's number
Given:
Number of atoms = 12.044 x 10^23
Substituting the values into the formula, we get:
Number of moles = (12.044 x 10^23) / (6.022 x 10^23)
Simplifying the Calculation:
When dividing numbers in scientific notation, we can simplify the calculation by dividing the coefficients and subtracting the exponents.
12.044 / 6.022 = 2
(10^23) / (10^23) = 10^(23-23) = 10^0 = 1
So, the simplified calculation becomes:
Number of moles = 2 x 1 = 2 moles
Therefore, 12.044 x 10^23 atoms of oxygen contains 2 moles of oxygen.
Conclusion:
The correct answer is option 'B', which states that 12.044 x 10^23 atoms of oxygen contains 2 moles of oxygen.

12.044 x 1023atoms of oxygen contains _______a)1 mole of oxygenb)2 mol...
One mole of any substance contains Avogadro’s number of particles. Its value is 6.022×1023 atoms. But here it’s given 12.044 x 1023 atoms, thereby dividing it by Avogadro’s number; 12.044 x 1023 atoms/6.022×1023 atoms = 2 moles. Hence it contains 2 moles of oxygen.
