Question

convert 12.043×10²² molecules of SO2 into moles

Answer 1

Answer:

1 mole = 6.023 × 10²³ molecules

According to the question,

The SO2 has 12.043 × 10²² molecules

⇒ Number of moles = 12.043 × 10²² / 6.023 × 10²³

⇒ Number of moles = 1.99 × 10⁻¹

⇒ Number of moles = 0.199 ≈ 0.2 moles

Hence the number of moles of SO2 in 12.043 × 10²² molecules is 0.2 approximately
