Which solution contains 0,1 mol of sodium hydroxide?
A- 1 cm3 of 0,1 mol dm3 NaOH
B 10 cm3 of 0,1 mol dm3 NaOH
C 100 cm3###################
d 100 cm3 ###################

Moles= Molarity*volume in dm^3

So what do we have to do in this case?

• chemistry. -

Your question asks for 0.1 mole. So I would multiply molarity x volume in dm^3 and see which equals 0.1 mole. By the way, the answer choices aren't very clear; for example, 0.1 mole dm^3 is what? Does that mean 0.1 mole/dm^3 or does it have another meaning?
