A 1.167 g sample contains only vitamin C ([tex]C_6H_8O_6[/tex]) and sucralose ([tex]C_{12}H_{19}Cl_3O_8[/tex]). When the sample is dissolved in water to a total volume of 35.9 mL, the osmotic pressure of the solution is 3.67 atm at 285 K.

What is the mass percent of vitamin C and sucralose in the sample?

Answer :

Final answer:

The mass percent of vitamin C and sucralose in the sample can be calculated using the given formula.

Explanation:

The mass percent of vitamin C and sucralose in the sample can be calculated using the formula:

Mass percent = (mass of component / total mass of sample) x 100

To find the mass of vitamin C, we can use the given mass of the sample and the molar mass of vitamin C. The molar mass of vitamin C (C6H8O6) is 176.12 g/mol.

mass of vitamin C = (molar mass of vitamin C / molar mass of sample) x mass of sample

To find the mass of sucralose, we can subtract the mass of vitamin C from the mass of the sample.

mass of sucralose = mass of sample - mass of vitamin C

Once we have the masses of vitamin C and sucralose, we can calculate their respective mass percentages.
