Oksi-84 [34.3K]

The volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L

  • If a single bottle of beer contains a total of 750.0 mL of beer, the volume of ethanol in the bottle is calculated as follows:

  • = 65/100 × 750

  • = 65 × 7.5

  • = 487.5mL

  • Therefore, volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L
