A 35 MGD surface Water treatement plant proposes to to use alum Coagulation for turbidity reduction using 44 mg/ L alum. the raw

water has an alkalinity of 80 mg / L as CaCO3. Commercial alum has the Formula Al2(SO4)3 X 18H2O (MW= 666).
A) determine the daily Alum Dosage Required in Kg/ day?

B) Using the Equivalent concept , how much alkalinity is used up by the alum added?

C) is the water alkalinity adequate. i.e , is it grater than the alkalinity consumed by alum?

What is the mass of 6 atom(s) of copper in grams?
USPshnik [31]

Answer:

6.33×10¯²² g

Explanation:

From the question given above, the following data were obtained:

Number of atoms = 6 atoms

Mass of copper (Cu) =?

From Avogadro's hypothesis, we understood that:

6.02×10²³ atoms = 1 mole of Cu

But 1 mole of Cu = 63.5 g

Thus,

6.02×10²³ atoms = 63.5 g of Cu

Finally, we shall determine the mass of 6 atoms of copper. This can be obtained as illustrated below:

6.02×10²³ atoms = 63.5 g of Cu

Therefore,

6 atoms = (6 × 63.5) / 6.02×10²³

6 atoms = 6.33×10¯²² g of Cu

Therefore, the mass of 6 atoms of copper is 6.33×10¯²² g.
