You have to go from grams --> moles --> molecules. You can find the equation online.

First you have to find the molar mass of AlF3 which is 83.98 g/mol.

To convert it to moles you simply

450.0 grams × $\frac{1 mol}{83.98 grams}$ = 5.358 mol

To convert mol to molecules: (multiply by Avogadros # = 6.022*10^23)

5.358 mol × $\frac{6.022*10^2^3}{1mol}$ = $3.23 *10^{24}$

What purpose does ammonia lauryl sulfate serve as a surfactor

Alborosie

Answer:

See below

Step-by-step explanation:

Ammonium lauryl sulfate has the structural formula CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂OSO₂O⁻ NH₄⁺.

The long nonpolar hydrocarbon chain and the ionic sulfate end group make it a surfactant.

The ionic end tends to dissolve in water, but the nonpolar chain does not. This makes the compound an excellent <em>foaming agent,</em> so it is used in many shampoos and toothpastes.

The molecules form <em>micelles</em> in water, small spherical shapes with the polar heads outside, facing the water, and the nonpolar tails are inside.

They reduce the surface tension or the water so that, when you brush your teeth or shampoo your hair, the air bubbles are stable and do not break.
