Question

the total no. of moles of O-atom in 16g of SO2 ore

Answer 1

________________________________________________________________

Here , Given Mass = 16 ( Sixteen ) grams

Molecular Mass = 32 + ( 16 × 2 ) = 64 grams

Now , Number of moles / –

• = Given Mass / Molecular Mass

• = 16 Grams / 64 Grams

• = 0.25 Moles

________________________________

Now , we know that one mole of SO² Contains 2 Moles ( two ) of atoms of oxygen .

Now , Number of moles of oxygen in 0.25 Moles of SO² / –

• = 2 × 0.25

• = 0.5 Moles

Hence , 16 Grams of SO² Contains 0.5 Mole(s) of Oxygen .
