How many oxygen atoms are there in 582 grams of caffeine (CH10N402, 194 g/mol)? Avogadro's Number: 1 mole = 6.02 x 1023 species
Sergeu [11.5K]

Answer:

3.61 * 10 ²⁴atoms.

Explanation:

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

w = 582 g

m = 194 g/mol

The number of moles can be calculated from the above formula , and substituting the respective values ,

n = w / m  = 582 g / 194 g/mol  =  3 mol

In the molecular formula of caffeine ,

<u>In 1 mole of caffeine their are - 2 moles of Oxygen. </u>

Therefore , in  3 moles of Caffeine there will be 6 moles of oxygen.

As well know ,

one mole of any substance contains 6.023*10²³ atoms,

Therefore , in  6 mol of oxygen =  6 * 6.023*10²³ atoms  = 3.61 * 10 ²⁴atoms.

Which of the following reactions is a synthesis reaction?
Vedmedyk [2.9K]
<h3>Answer:</h3>

B) 4H₂(g) + O₂(g) ⟶ 2H₂O(l)

<h3>Explanation:</h3>
  • Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
  • Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
  • In our case, we were supposed to identify a synthesis reaction.
  • Thus, we need to know what is a synthesis reaction.
  • A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
  • In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.

Answer:

PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.
