The number of micrograms of contaminant each person will receive is 5,742.64 ug.
<h3>
Number of micrograms of contaminant per person</h3>
The number of micrograms of contaminant each person will receive is calculated as follows;
Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L
Amount of contaminant (mg) = 2.3028 mg.L/mL
Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg
Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug
<h3>Amount of contaminant per person (ug/person) </h3>
= (2,302,800 ug) / (401 persons)
= 5,742.64 ug per person

Since that is a lengthy one I to have the same problem in chem. I always trust google and ask question but question of the elements of the periodic table and one by one it will give you the answer and will tell you the formula and the cations
Mass of ammonium sulfate = 660.7 g
<h3>Further explanation</h3>
Given
3.01 x 10²⁴ molecules of ammonium sulfate
Required
mass
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol ammonium sulfate (NH₄)₂SO₄ :
n = N : No
n = 3.01 x 10²⁴ : 6.02 x 10²³
n = 5
mass ammonium sulfate :
= mol x MW
= 5 x 132,14 g/mol
= 660.7 g
Answer: C. Al (aluminum)
Explanation: it has 3 valence electrons :)
Answer:
C
Explanation:
The electrons in an atom are specifically housed in locations that could be referred to as shells. These shells are the places where we can find an electron.
Now, within each shell, we have different energy levels in which these occupants electrons occupy. These energy levels have different energies and the amount of electrons they can take.
For example, the number of electrons S can take is 2 while that in which d can take is 10
