<u>Answer:</u> The mass of sucrose required is 69.08 g
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

Or,

where,
= osmotic pressure of the solution = 8.80 atm
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (sucrose) = ?
Molar mass of sucrose = 342.3 g/mol
Volume of solution = 564 mL (Density of water = 1 g/mL)
R = Gas constant = 
T = Temperature of the solution = 290 K
Putting values in above equation, we get:

Hence, the mass of sucrose required is 69.08 g

D - matter remains constant in any chemical equation, so reactants always equal products.
The substance that will form a solution when mixed with solid sodium chloride would be CH₂OH
<h3>Solubility of NaCl</h3>
A solution is only formed when a solute dissolves in a solvent.
In this case,
and CH₂OH are the only liquid solvents. However, NaCl is insoluble in
while it is soluble in CH₂OH due to its polarity.
Thus, NaCl can form a solution only with CH₂OH.
