Question

Calculate the number of potassium atom in 122.5g of kclo3

Answer 1

Answer:

6.022 × 10²³

Explanation:

No. of atoms = given mass / molar mass × 6.022×10²³

Answer 2

$\huge\red{\boxed{\bold{Solutions}}}$

No. Of mes of KClO3 = 122.5/122.5 = 1

(mol. Wt of KClO3 = 122.5)

$\large\underline\mathrm\blue{From \: the \: formula \: KClO3, \: we \: know \: that \: 1 }$

$\large\underline\mathrm\blue{more \: of \: KClO3 \: contains \: 1 \: mole \: of \: K \: atoms, \: 1 }$

$\large\underline\mathrm\blue{mole \: of \: Cl \: atom \: and \: 3 \: moles \: of \: O \: atoms.</p><p>}$

(1.). No. of k = 1 × 6.022 × 10^23

(2.). No. of Cl = 1 × 6.022 × 10^23

(3.). No. of O = 1 × 6.022 × 10^23
