Question

Find the number of particles in 92g of sodium atom.​ (with process).

Answer 1

Answer:-

2.4088×10²⁴ particles

Explanation:-

• Atomic mass of Sodium (Na) = 23u

We know that, molar mass of an element is the atomic mass in grams. Thus, molar mass of Sodium is 23g.

Number of moles in 92g of sodium :-

= Given Mass/Molar mass

= 92/23

= 4 moles

Thus, 4 moles are there in 92g of Sodium.

• Avogadro number = 6.022×10²³

Number of particles:-

= No of moles × Avogadro number

= 4×6.022×10²³

= 24.088×10²³

= 2.4088×10²⁴ particles

Thus, 2.4088×10²⁴ particles are there in 92g of Sodium atoms.
