All shampoos have alkaline already in them for cleaning your hair, although a strong amount of alkaline can damage your hair. The water also has alkaline in it already. While the alternative product is more acidic it does not clean as well. Overall Alkaline is best for the cleaning of hair.

A solution contains 45 grams of nitrogen gas and 40 grams of argon. What is the mole fraction of argon in this solution?

Katarina [22]

<span>0.38

You first calculate the total moles by dividing the grams by molecular weight:
45 g N2 / 28.02 g/mol = 1.6 mol N2
40 g Ar / 39.95 g/mol = 1.0 mol

Then you divide the moles of Ar by the total number of moles:
1.0 / (1.6 + 1.0) = 0.38 mol fraction</span>
