Question

convert 12.044 x 1022 molecules of sulphur dioxide into moles (S=32u,O=16u)​

Answer 1

Answer:

0.2 moles

Explanation:

We know that,

1 mole of SO2 Contains 6.022 X 10²³ Molecules

Therefore,

No. of Moles = No. of Molecules/ 6.022 X 10²³

= 12.044 X 10 ²³ / 6.022 X 10²³

= 0.2 moles

Answer 2

Answer:

12.8 moles

Explanation:

no. of molecules of SO^2: 12.044×10^22

mass no. of Sulphur= 32u

mass no. of oxygen= 16 = 16×2= 32u

=(32+32) g

mass no. of SO^2=64g

Avagardo constant = 6.022×10^23

=(12.044×10^22/6.022×10^23) × 64

=64/5

=12.8 moles

// hence //
