Question

How many moles of ethanol C2H6O, are in a 10.0g sample​

Answer 1

Answer: 0.217 mol

Explanation:

To find the amount of moles in a 10 g sample, we need the molar mass of ethanol.

Molar Mass: 46.07 g/mol

Now that we have the molar mass, we can find moles.

$10.0 g*\frac{1mol}{46.07g}=0.217 mol$

We know that there are 0.217 mol in a 10.0 gram sample.
