Explanation:
1.00 mole of O2 contains 2 × 6.023 × 10²³ atoms
= 12.046 × 10²³
In option A
No of oxygen atoms= 0.667 × 3 × 6.023 × 10²³
= 12.046× 10²³ ✓
In option B
No of oxygen Atoms = 1 × 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
In option C
No of oxygen atoms= 2 × 6.023 × 10²³
= 12.046 × 10²³ ✓
So option D is correct
1.00 mole of O2 contains the same number of oxygen atoms as A) 0.667 mole of O3.
Mole concept
A mole is a unit of measurement used to measure the amount of any fundamental entity (atoms, molecules, ions) present in the substance. A mole is very much similar to the concept of weight, as both help in understanding the amount of a substance present.
1 mole of O2 =6.022* 10^23 O2 molecules
1 O2 molecule contains 2 O atoms
Therefore,
No. of O atoms in 1 mole of O2 molecule = 22 *2*6.010^ 23 atoms
1.00 mole of O2 = 0.667 mole of O3
12.044*10^23 atoms answer
1.00 mole of CH3CO2H = 8 × 6.022^ 23 atoms
2.00 mole of CH3CH2OH = 2×8 × 6.010^ 23 atoms
What is mole explain with example?
One mole is defined as the amount of substance containing as many elementary entities atoms, molecules, ions, electrons, radicals, etc.
