Use M1V1=M2V2
(2.5M)(X)=(0.1)(0.50M)
X=(0.1)(0.50)/2.5
X-0.02 L or 20 ML
2O ML.
If you are too lazy to find (and use) the caps key in chemistry it can lead to serious problems. If m should be M (M = MOLAR; m = MOLAL) the answer provided by Wrinkly is correct. The same applies to things such as Co = cobalt, CO = carbon monoxide, co = company, etc. Beware.
