The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

Had Richard Donner completed the Superman sequel back in 1979, it very likely would have been a better film than what Lester ultimately made but 2006's The Donner Cut is simply the best one could do 26 years later. It's also a bit jarring to see test footage in the middle of a movie.
Computer programmer Gus Gorman (Richard Pryor) is hired by financial tycoon Ross Webster (Robert Vaughn) to seize control of a weather satellite and annihilate Colombia's coffee crop. When Superman (Christopher Reeve) manages to thwart the plan, Webster commands Gorman to use the satellite to locate kryptonite, the Man of Steel's mortal weakness. But a missing unknown element in the kryptonite replaced by Gorman with tar causes an unintended side effect when presented to Superman.

A medication for which the nurse will educate the caregivers of a child diagnosed with rheumatic fever is aspirin.
<h3>What is a drug?</h3>
A drug can be defined as a type of chemical substance (medication) that is designed and administered to provide wellness and healing to a sick person.
In this scenario, we can infer and logically deduce that a medication for which the nurse will educate the caregivers of a child that is diagnosed with rheumatic fever is aspirin such as salicylates.
