anonymous · Answer

what's p

aaronq · Answer

density

aaronq · Answer

g is gravity

i did that but still got it wrong

@cleverchuck , welcome to openstudy. 

Please let us know what you tried yet in solving the question, the formula given by @aaronq should work, what values did you put on the place of 'p' , 'g' and 'h' ?

Well first of all , what is osmotic pressure?

Osmotic Pressure $(\bf \pi)$ is the pressure required to prevent the osmosis from occurring.

$\bf \pi$ = $\rho g h$ 

$\rho = \textbf{density}$ 
$g = \textbf{ acceleration due to gravity} $
$h = \textbf{height (here it is given)}$ 


Now, you know the density of the water , (but note , you have to put the value according to the units as the height is given in metres , so you have to put the value of the density of water having unit $kg m^{-3} $ ) 

the acceleration due to gravity = g (I hope you know the value of it) 
and the "h" that is given here. (105 metres )

Just solve for it and it must be right.
