1 mole of Na contains Avogadro number of Na atoms

i.e. 1 mole of Na contains 6.023 x 10²³ Na atoms

So, 45 moles of Na contains 45 x 6.023 x 10²³ Na atoms

= 2.71 x 10²⁵ atoms of Na

Hope it helps!

Answer:

Number of particle present in 45 mole of sodium =2.7099 ×10²⁵

Explanation:

Number of particle present in 45 mole of sodium                                                                                                                                                                                                                  

                                                                         = Avagrado's no × no. of moles    

                                                                         = 6.022×10²³ × 45

                                                                         = 270.99 ×10²³

                                                                         = 2.7099 ×10²⁵

∴Number of particle present in 45 mole of sodium =2.7099 ×10²⁵
