>A 1.10-g sample contains only glucose (C6H12O6) and sucrose (C12H22O11). When a sample is dissolved in water to a total solution volume of 25.0 mL, the osmotic pressure of the solution is 3.78 atm at 298 K. What is the percent mass of the glucose in the sample, and what is the percent mass of sucrose in the sample?

Mass percentage of glucose : 22.3%

Mass percentage of sucrose:77.7%

Explanation:

Mass of glucose in sample =

Mass of sucrose in sample = y

Mass of sample = 1.10 g

x + y = 1.10 g ..[1]

Osmotic pressure of the solution =

Volume of the solution = 25.0 mL = 0.025L ( 1 mL = 0.001 L)

Temperature of the solution =T = 298 K

..[2]

Solving [1] and [2] we get :

x = 0.2453 g

y = 0.8547 g

Mass percentage of glucose :

Mass percentage of sucrose:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
