Question

Which contains the greatest number of moles of oxygen atoms 1 mol of ethanol​

Answer 1

1 mole of Formic Acid. 1 mole of the Ethanol contains 1 mole of the Oxygen atoms

Answer 2

. 1 mol of ethanol

C2H5OH (ethanol) – Molar mass

= 24 + 6 + 16

= 46

46 g of ethanol contains 1 × 6.023 × 1023 number of oxygen atoms.

2. 1 mol of formic acid.

HCOOH (formic acid) – Molar mass

= 2+12 + 32

= 46

46 g of HCOOH contains 2 × 6.023 × 1023 number of oxygen atoms.

3. 1 mol of H2 O

H2O (water) – Molar mass

= 2 + 16

= 18

18 g of water contains 1 × 6.023 × 1023 number of oxygen atoms.

∴ 1 mole of formic acid contains the greatest number of oxygen atoms.
