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

Answer:
B?
Explanation:
it just makes the most sense in my head
To balance a chemical reaction, it is important to remember that the number of atoms of each element in the reactants and the product side should be equal. This is to follows the law of conservation of mass where mass cannot be created or destroyed. So, the total mass that is used to react should have the same value of the total mass of the substances produced from the reactants. The balanced chemical reaction would be written as follows:
<span> 2h2 + o2 = 2h2o
Reactant = Product
H = 4 = 4
O = 2 = 2
Therefore, the correct coefficient for the hydrogen gas would be 2.</span>
Salt and water are formed
H₃PO₄ + 3KOH = K₃PO₄ + 3H₂O
CH₃COOH + NaOH = CH₃COONa + H₂O
