Answer: 1.31
Explanation:
No.of moles = given no.of atoms/Avagadro number
= 7.91×10^23 / 6.022 x 10^23
= 1.31
therefore, no.of moles = 1.31
Hope it helped u,
pls mark as the brainliest

The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.
(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
Therefore, true. (Also would u mind giving brainliest, you don't have to hehe)
For me the answer is E. It is composed of one Ru2+ ion and two F- ions.
The amount of kinetic energy that an object has depends on its mass or how heavy it is and how fast it is moving, or velocity
