Question

calculate the number of particles
46g of sodium (Na)atom​

Answer 1

Answer:

molar mass of sodium 23g per mol.

given moss of sodium is 46g the number of particles present in 46g of Na atom is 12.046 into 1023

Answer 2

Question ⤵️

Calculate the number of particles

alculate the number of particles 46g of sodium (Na)atom.

$\huge \boxed{ \pink{Answer}}$

Given that ,

Mass of Na = 46 g

Molar mass of Na = 26 g/mol

Therefore , number of moles (n) =

mass of Na / molar mass of Na

= ) 46/23

= ) 2 mols

Number of Na atoms = n × n(a)

= 2 × 6.022 × 10²³ atoms

= 1.2044 × 10²⁴ atoms ✔️
