What volume of 0.210 M ethanol solution contains each of the following number of moles of ethanol?
A 0.45 mol ethanol
B 1.25 mole ethanol
C 1.3X10^-2 ethanol
M stands for Molarity (amount of mol/l or mmol/ml)
In this case with 0.210M ethanol solution it means that 1l of your solution contains 0.210 mol of ethanol.
a.) (0.45 mol/ 0.21 mol)* 1l
Am sure you are able to calculate the other 2 yourself
By the way the answer above has gotten soemthing mixed up 22.4 is the volume of a gas at standard condition.Ethanol is a liquid also known as alcohol

well if it is at STP
u would use Molarity m=mass/volume
.210=m/22.4L
and then you would convert the mass u get in grams to moles
M stands for Molarity (amount of mol/l or mmol/ml)
In this case with 0.210M ethanol solution it means that 1l of your solution contains 0.210 mol of ethanol.
a.) (0.45 mol/ 0.21 mol)* 1l
