A solution of 6.85g of a carbohydrate in 100.0g of water has a density of 1.024 g/mL and an osmotic pressure of 4.61 atm at 200C. Calculate molar mass of the carbohydrate

Explanation:

Hello,

In this case, since the solute is a carbohydrate the van't Hoff factor is 1, therefore, osmotic pressure, defined via:

Allows us to compute the molarity of the carbohydrate in the solution:

Next, with the computed molarity, we can compute the volume in liters of the solution with the mass of the carbohydrate and water:

After that, we compute the moles of the carbohydrate:

Finally, we compute the molar mass with the obtained moles and the given mass of carbohydrate:

Regards.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
