Answer:

c. 0.30

Explanation:

One C atom has a mass of 12.0 u and one Ar atom has a mass of 40.0 u.

Let’s assume that there are <em>n</em> atoms of C and <em>n</em> atoms of Ar. Then

Mass of <em>n</em> C atoms = <em>n</em> × 12.0

Mass of <em>n</em> C atoms = 12.0<em>n</em> u

Mass of <em>n</em> Ar atoms = <em>n</em> × 40.0

Mass of <em>n</em> Ar atoms = 40.0<em>n</em> u

ratio = mass of C/mass of Ar

ratio = 12.0<em>n</em>/40.0<em>n </em>

ratio = 0.300

Shtirlitz [24]

Answer:

Synthetic detergents can be used for washing purposes even when the water is hard, whereas soaps are not suitable for washing with hard water. This is because of the fact that synthetic detergents can lather with hard water. Hence, Synthetic detergents better than soaps.
