Answer:

25 g/hr

Explanation:

Remember that the rate of reaction refers to the rate at which reactants are used up or or the rate at which products appear.

Hence;

Rate of reaction = mass of reactant used up/time taken

Mass of reactant used up= 2g

Time taken = 5 minutes or 0.08 hours

Rate of reaction = 2g/0.08 hours = 25 g/hr

1.0g of a protein is dissolved in 100 ml of distilled water. The resulting solution has an osmotic pressure of .001 atm. What is
Svetlanka [38]

The osmotic pressure π, is related to concentration i.e. molarity (M) through the following equation:

π = MRT ------(1)

where R = gas constant = 0.0821 L atm/mol-K

T = temperature (let us assume 25 C = 25 + 273 = 298 K)

M = π/RT = 0.001/0.0821 * 298 = 4.09 * 10^-5 M

Now,

molarity = moles of solute/volume of solvent in Liters

            = (mass of protein/molar mass)/volume

4.09 * 10^-5 moles/L = (1.0 g/molar mass)/0.1 L

Molar mass of protein = 2.445 * 10^5 g/mole
