Explanation:
Given
2500 meters
200 grams
Required
How do they compare?
You can't compare these two measurements in terms or size, units and measurements because they measure two different quantities
2500 meters measures length or distance
while
200 grams measures mass of objects
I would love to help but I cant see the picture
The osmotic pressure is a colligative property which depends upon the number of molecules and not the type of molecules
The relation between osmotic pressure and concentration is
πV = nRT
where
π = Osmotic pressure [ unit atm] = ?
V = volume
n = moles
R = gas constant = 0.0821 L atm / mol K
T = temperature = 20°C = 20 + 273.15 K = 293.15 K
also
Molarity = moles / Volume
So
Molarity = n/V = 5.5 M
Putting values
π = MRT
π = 5.5 X 0.0821 X 293.15 = 132.37 atm
Osmotic pressure of given glucose solution will be 132.37 atm
A.) Average acceleration = change in velocity/time = final velocity - initial velocity/time = 10-0/4 = 10/4 = 2.5m/s^2.
Using ideal gas equation,
PV=nRT
P=199 kpa
V=4.67 L
T=30+273K= 303K
n= number of moles of gas
R=8.321 L·kPa·K-1·mol-1
So using ideal gas equation,
n=PV/RT
=199*4.67/8.321*303\
=0.37 mol
