calculate the number of atoms in 45 moles of Na
Answers
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
