So to solve for this, we are going to use the formula of osmotic pressure.
00:06
Osmotic pressure is equivalent to phantalque factor of our salute, which is the organic polymer, multiplied by the malarity of the solution, and then are the constant and see the temperature.
00:21
So we are calculating the molar mass of our salute, the polymer.
00:26
So i'm going to rearrange this first and calculate for malarity.
00:30
Of the solution so that means this is equivalent to this multi pressure divided by bantoc factor i and then r c okay so in the information that we have we have a 560 this is m mhm this is dose monic pressure compared this to atm because r is in terms of atm 760 mhmg is equivalent to 1 atm so that means you could cancel this now divided by i for the polymer will just be 1 okay r is 0 .0 821 meters at m for mold kelvin and then the temperature we have 21 degrees celsius so we add to 703 for this to be in kelvin so that means we cancel this and then atm okay and as you can see there many units are moles and meters so malarity is equivalent to 4 .70 times 10 to the negative 4.
01:41
This is moles per liter.
01:44
Okay, that's malaria.
01:45
Remember, malaria is equivalent to moles up, solute over the volume of the solution, which should be in liters.
01:55
So let's equate that 4 .70 times 10 to the negative 4, 6 moles per liter, we'll calculate the moles of our salute.
02:06
Over the volume of the solution.
02:08
So we have 202ml.
02:10
We need to convert this to liters...
