The atomic mass of sulfur is 32.1 amu, and the atomic mass of oxygen is 16.0 amu. To the nearest tenth of a percent, what is the

Zielflug [23.3K]

Answer:

$\%\ Composition\ of\ sulfur=40.1\ \%$

Explanation:

Percent composition is percentage by the mass of element present in the compound.

Given , Mass of sulfur= 32.1 amu

Mass of oxygen = 16.0 amu

Mass of sulfur trioxide $SO_3$ = 32.1 amu + 3*16.0 amu = 80.1 amu

$\%\ Composition\ of\ sulfur=\frac{Mass_{sulfur}}{Mass_{SO_3}}\times 100$

$\%\ Composition\ of\ sulfur=\frac{32.1\ amu}{80.1\ amu}\times 100=40.1\ \%$

How is precipitation useful in our daily lives?

Alex73 [517]

Answer:

The precipitation reaction is the double displacement reaction in which two ionic bonds combine forming up insoluble salts.

Precipitation reaction can be used in our daily life in events such as in waste water treatment. When a contaminant forms an insoluble solid, then we can use this reaction to precipitate out the contaminated ions.

The rings which form in the bathtubs are also an example of the precipitation reactions.
