How many moles are there in 4.01 x 1024 atoms of zinc?
1 answer:
<span>Answer is 6.66 mol.
<em>Explanation:</em>
According to the
Avogadro's constant, 1 mole of substance has 6.022 × 10²³ particles.
Number of Zinc atoms = </span>4.01 x 10²⁴
Avogadro's constant = 6.022 × 10²³ mol⁻¹
Hence,
moles of Zinc = number of Zinc atoms / Avogadro's constant
= 4.01 x 10²⁴ / 6.022 × 10²³ mol⁻¹
= 6.66 mol
