How many moles are in 1.50 grams of ethanol, ch3ch2oh?

The number of moles of ethanol for given amount is 0.0326 moles.

Explanation:

To calculate the number of moles, we use the equation:

We are given:

Given mass of ethanol = 1.50 g

Molar mass of ethanol = 46.07 g/mol

Putting values in above equation, we get:

Hence, the number of moles of ethanol for given amount is 0.0326 moles.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
