Answer:

12 Oxygen Atoms

Explanation:

We need to figure out how many atoms of Al, S and O are represented by the these two similar formulas:

Al2(SO4)3:

Al2 means 2 aluminums, (SO4)3 means 3 (SO4)s. The grand tally: 2 aluminum atoms + 3 sulfur atoms + 12 oxygen atoms = 17 atoms total in each molecule.

Hope this helps!

If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the
vampirchik [111]

Answer:

<h2>0.87 atm </h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question

2.47 L = 2470 mL

We have

P_2 =  \frac{765 \times 2.78}{2470}  =  \frac{2142}{2470}  \\  = 0.867206...

We have the final answer as

<h3>0.87 atm</h3>

Hope this helps you

IrinaVladis [17]

A unit of ppm has an acronym of parts per million. The equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:

mass Ca+ = 1.3 g = 1300 mg

 

ppm = 1300 mg / 3100 kg

<span>ppm = 0.42 ppm</span>
