Question

Convert
$12.043 \times {10}^{22} mol.$
of sulphur dioxide into moles.​

Answer 1

ANSWER

1mole of SO2 = 6.022×10^24 molecules

or,

6.022×10^23molecules= 1 mole of SO2

1 molecule = 1/6.022×10^23 mole of SO2

12.043×10^22 molecules=1/6.022×10^23×12.043×10^22 moles of SO2

= 0.2 moles of SO2

Answer 2

Here,

In context of sulphur dioxide                                

6·022 × 10²³ molecules = 1 mole

∴ 12·043 × 10²² molecules = 12·043 × 10²² /6·022 × 10²³

                                             = 0·2 moles.

                   

Hope it helps
