A mouthwash is 21.6% by mass alcohol.  If each bottle contains 0.358 pints of mouthwash with a density of 0.876 g/mL, how many kilograms of alcohol are in 180 bottles of the mouthwash

1 pint = 568.26125 ml so 0.358 pints = 0.358*568.26125 ≈ 203.438 ml

 

mass of mouthwash in a bottle = 0.876 g/ml x 203.438 ml = 178.211 g

 

mass of alcohol in a bottle = 0.216 x 178.211 g = 38.494 g

 

mass of alcohol in 180 bottles = 180 x 38.494 g = 6928.854 g  or  approximately 6.929 kg
