How many helium atoms are there in a helium blimp containing 536 kg of helium? n = atoms?
Mariulka [41]

Answer:- 8.07*10^2^8atoms

Solution:- It is a unit conversion where it asks to convert kg of He to atoms. We need to convert kg to grams, grams to moles and finally moles to atoms.

We know that, 1 kg = 1000 g

Molar mass of He is 4.0 grams per mole and 1 mole of an atom equals to Avogadro number of atoms.

The set up would be as given below:

536kg(\frac{1000g}{1kg})(\frac{1mole}{4g})(\frac{6.02*10^2^3atoms}{1mole})

= 8.07*10^2^8atoms

So, there are 8.07*10^2^8atoms of He in it's 536 kg.

Vesnalui [34]

Hyperbaric oxygen therapy increases the blood's capacity to carry and deliver oxygen to compromised tissues. this therapy may be used for a client with a skin graft that is impaired.

<h3>Define Hyperbaric oxygen therapy.</h3>

Hyperbaric oxygen therapy (HBOT) is a sort of treatment used to hasten the recovery of infections where tissues are oxygen-starved, gangrene, wounds that won't heal, and carbon monoxide poisoning. You enter a special chamber for this therapy where the air pressure is 1.5 to 3 times greater than usual, allowing you to breathe only pure oxygen.

<h3>How is aging impacted by hyperbaric oxygen therapy (HBOT)?</h3>

Telomere length (TL) shortening and cellular senescence are two crucial signs of aging at the cellular level. Using specific hyperbaric oxygen therapy (HBOT) protocols, repeated intermittent hyperoxic exposures can cause the regenerative effects that happen during hypoxia.
