Question

Calculate total moles of atom present in 245g of KClO3
?[mass of K=39,Cl = 35.5 ,O =16]

Answer 1

Answer:

39+35.5+16*3

122.5 is the answer

Answer 2

Answer:

Explanation:

Molar mass of KClO₃ = 122.5 g/mole

Now, the no. of moles of KClO₃ = 245/122.5 = 2 moles

now, there will be 2 moles of Chlorine atoms, => 2 x 6.022 x 10²³ atoms = 12.044 x 10²³ atoms

now, there will be 2 moles of potassium atoms, => 2 x 6.022 x 10²³ atoms = 12.044 x 10²³ atoms

there will be 2 x 3 moles of oxygen= 6 moles = 6 x 6.022 x 10²³ atoms = 36.132 x 10²³ atoms
