Explain in terms of intermolecular forces the following: Why NaI has a higher melting point than I2 Because NaI can form hydroge

n bonds, and I2 cannot. Because NaI is an ionic compound, and the ion-ion attractions are much stronger than the dispersion forces between the I2 molecules. Because NaI is a solid, and I2 is a liquid. Because NaI is soluble in water, and I2 is not.

il63 [147K]

Answer : The mass of Allura Red present in an 10 fluid ounce glass of the beverage is, 7.634 mg.

Explanation : Given,

Volume of solution = 10 fl oz = 295.735 mL

Molar mass of Allura Red = 496.42 g/mole

Concentration of Allura Red (Molarity) = 0.000052 M

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of Allura Red}\times 1000}{\text{Molar mass of Allura Red}\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

0.000052M=\frac{\text{Mass of Allura Red}\times 1000}{496.42g/mole\times 295.735mL}

\text{Mass of Allura Red}=0.007634g=7.634mg

Therefore, the mass of Allura Red present in an 10 fluid ounce glass of the beverage is, 7.634 mg.
