I have a beaker separated into 2 halves by a partially permeable membrane. On one half I fill 500 ml of distilled water. On the other half I fill 100 ml of distilled water. The question is will osmosis take place? My friend says no because the concentration is same. However doesn't volume affect concentration because the formula for concentration is g/dm3? so will osmosis take place? Pls explain thx.

OSMOSIS - the diffusion of water particles through a partially permeable membrane
DIFFUSION - the net movement of particles from an area of low to high concentration
Osmosis will NOT take place because the concentration of the water on both sides of the partially permeable membrane are the same (so the concentrations are basically already in equilibrium so osmosis will not take place). Volume doesn't affect concentration, because you can have 500ml, 300ml, 100ml etc. of really high concentrated liquid and it will still be really high concentrated liquid.
and g/dm3 only refers to how many grams of ANOTHER SUBSTANCE DISSOLVED IN WATER there is in every decimeter cubed of water. So in this case, because it is distilled water, it should be 0g/dm3 on both sides of the partially permeable membrane which means that the concentration is the same on both sides which means that no, osmosis will NOT take place.

the osmosis is related to osmotic pressure which is a colligative property(the property that depends only on particles or molecules present in solution.)
conc. depends on the volume as u say..but here the ratio particles to volume is same.
its like 2 molecules in 10 ml and 4 molecules in 20 ml..so the is same...
hope u get!

Volume does matter to an extent. If the reservoirs on each side are of similar volume than each side will end up with 300ml to even out the pressure of each. Something like added salt would need to be in the 500ml end to keep that volume there

No, volume will affect concentration only of there are other particles mixed with water, if it is distlled water no matter how big or small the volume is the concentration will always be 100% water nothing else
