Convert 3.2 moles of ch4 to number of molecules
REY [17]

Answer: 1.93 x 10^24 molecules

Explanation:

CH4 is the chemical formula for methane, the first member of the alkane family.

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 molecule

So, 1 mole of CH4 = 6.02 x 10^23 molecules

3.2 moles of CH4 = Z

To get the value of Z, cross multiply:

(Z x 1 mole) = (6.02 x 10^23 molecule x 3.2 moles)

Z•mole = 19.26 x 10^23 molecules•mole

Divide both sides by 1 mole

Z•mole / 1 mole = 19.26 x 10^23 molecules•mole/ 1mole

Z = 19.26 x 10^23 molecules

Place Z in standard form

Z = 1.93 x 10^24 molecules

Thus, 3.2 moles of ch4 has 1.93 x 10^24 molecules

For the element chlorine to be "happy", it needs 8 valence electrons meaning it needs 8 electrons on its outer shell. So the answer would be chlorine because it has 7 valence electrons in the picture and it needs one more to be considered stable.
