Um your best answer that i know will be in sat so idk how to explain this to you (p.s i am filming a youtube vid check it out Hailey Tarlton go subscribe
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

Idiopathic pulmonary fibrosis is a chronic, deadly condition that causes a steady loss in lung function.
The phrase pulmonary fibrosis refers to lung tissue scarring and is the cause of worsening dyspnea (shortness of breath). Fibrosis is commonly connected with a dismal prognosis.
