in 10.0 mL of methanol, how many moles of methanol are there?

Question

Methanol, CH4O is a liquid at room temperature and its density is 0.792 g/mL

Answer 1

I will give you the steps to answer this, but YOU do the calculations.

 

Get the mass in grams of methanol by multiplying its density by the given volume.

 

Get the molecular weight of methanol in grams per mole.  Look it up, or add atomic weights in grams per mole:

 

C + 4H + O

 

Divide the mass in grams by the molecular weight in grams per mole.  The result is the number of moles that you have in the given volume.
