Beer

After three 10° beers consumed in a short time, there is 5.6 g of alcohol in 6 kg adult human blood. How much is it per mille?

Correct result:

p =  0.9

Solution:

m1=5.6 gkg=5.6/1000 kg=0.0056 kg m2=6 kg  p=1000 m1m2=1000 0.00566=1415=0.9 ‰m_{1}=5.6 \ g \rightarrow kg=5.6 / 1000 \ kg=0.0056 \ kg \ \\ m_{2}=6 \ \text{kg} \ \\ \ \\ p=1000 \cdot \ \dfrac{ m_{1} }{ m_{2} }=1000 \cdot \ \dfrac{ 0.0056 }{ 6 }=\dfrac{ 14 }{ 15 }=0.9 \ ‰
