Question 107 of 200

Multiple Choice

N₂

3.31%

Explanation:

The number of molecules is given by the formula:

Number of molceules = moles x avogadros constant

Since all of the given elements have the same number of moles all of them will have the same number of molecules, which will be 6.02 x 102^3, the Avogadros constant.

H₂

9.46%

Explanation:

The number of molecules is given by the formula:

Number of molceules = moles x avogadros constant

Since all of the given elements have the same number of moles all of them will have the same number of molecules, which will be 6.02 x 10²³, the Avogadros constant.

O₂

6.28%

Explanation:

The number of molecules is given by the formula:

Number of molceules = moles x avogadros constant

Since all of the given elements have the same number of moles all of them will have the same number of molecules, which will be 6.02 x 10²³, the Avogadros constant.

Number of molecules are equal
