Question

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

Answer 1

Answer: 0.217 mol

Step-by-step 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*(1mol)/(46.07g)=0.217 mol`

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