Answer:
3.481 x 10²⁴ atoms
Explanation:
Data Given:
Number of moles of NH₄NO₃ = 5.78 mol
Number of atoms of NH₄NO₃ = ?
Solution:
Formula used
no. of moles = no. of atoms / Avogadro's number
As we have to find no. of atoms
So, we have to rearrange the above equation
no. of atoms = no. of moles x Avogadro's number . . . . . (1)
Where
Avogadro's number = 6.022 x 10²³ atoms
Put values in above Equation 1
no. of atoms = 5.78 mol x 6.022 x 10²³ atoms/mol
no. of atoms = 3.481 x 10²⁴ mol
So,
no. of atoms in 5.78 mole NH₄NO₃ = 3.481 x 10²⁴ atoms
Answer:
The answer is 3.48 × 10²⁴
Explanation:
Avogadro's constant/number is used to get the actual number of particles (atoms or ions) in a molecule of a substance.
Avogadro's number is 6.022 × 10²³
To get the actual number of atoms in a substance: avogadro's constant is multiplied by the number of moles of the substance
Hence,
number of atoms = 5.78 × 6.022 × 10²³
number of atoms in 5.78 moles of NH₄NO₃ = 3.48 × 10²⁴
