The average adult male has a total blood volume of 5.0 l. after drinking a few beers, he has a bac of 0.10. what mass of alcohol is circulating in his blood?

5 grams  of alcohol is circulating in his blood

Explanation:

BAC (Blood alcohol content) means that level of alcohol in the blood stream.

Given BAC of an adult male = 0.10 = 0.10 g/100 ml

Total blood volume = 5 L = 5000 ml

MAss of alcohol in 5000 ml of blood:

5 grams  of alcohol is circulating in his blood

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
