A whiskey distillery in Dublin went into flames and released a river of whiskey, crowds gathered along the stream of alcohol to scoop up the liquor using caps, porringers, and other vessels. In all, 13 people died, not because of the fire, but ofalcohol poisoning. a. If the average human weights 137 pounds, the Human LD50 of ethanol is ~2000mg/kg. And the typical content of alcohol in whiskey is 40% . How much alcohol does the average human must drink to succumb to alcohol poison. Assume the density of whiskey is 1 so that 1 ml of whiskey is 1 gram of whiskey. In addition, assume that the LD50 is the amount required to succumb to alcohol poison.
- What's the differences between two questions? Q1) How much calcium would you ingest by drinking one 8 oz glass of your tap water? Show all calculations. -->Tap water 8Oz = 8 x 0.0296L = 0.2368L Hardness = 66.73ppm = 66.73mg/L CaCO3 1L has 66.73mg CaCO3 0.2368L has 66.73mg x 0.2368 = 15.8017mg MW of CaCO3 = 100g/mol MW of Ca = 40g/mol 100g CaCO3 has 40gf of Ca 15.8017mg CaCO3 has 40/100 x 15.8017mg Ca We would ingest 6.321mg of Ca. Q2) What percentage of the recommended daily dose of calcium (1,150 mg/day) does 1.0 L of your water provide? Show all calculations. --> 66.73mg/1150mg x 100 = 5.80% My Question) Why this calculation is wrong? I think this calculation is same with question 1. Isn't it? CaCO3 = 100g/mol, Ca = 40g/mol 100g CaCO3 has 40g Ca. 66.73 CaCO3 has 40/100 x 66.73mg Ca Ca = 26.70mg 26.70mg/1150mg x 100 = 2.32%Given the following data, what is the molarity?
