Interpretation:
Using osmotic pressure, the empirical formula for sucrose is same as its molecular formula has to be shown.
Concept introduction:
Osmosis is the process by which net movement of solvent into an expense of higher solute concentration via semi permeable membrane.
Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,
Osmotic pressure:
Where,
‘i’-Van’t Hoff factor.
M – Molarity of the solution (mol/L).
R- Ideal gas constant (0.08206
T-Temperature in Kelvin
Moles: One mole is equivalent to the mass of the substance consists same number of units equal to the atoms present in
From given mass of substance moles could be calculated by using the following formula,
Mass: It is the quantitative measure of a substance. The amount of matter present in substance is expressed as mass. The
