Question

a blood concentration of 0.065 M ethyl alcohol is sufficient induce a coma. at this concentration , what is the total mass of alcohol in grams in an adult male whose total blood volume is 5.6L? a blood concentration of 0.065 M ethyl alcohol is sufficient induce a coma. at this concentration , what is the total mass of alcohol in grams in an adult male whose total blood volume is 5.6L? a blood concentration of 0.065 M ethyl alcohol is sufficient induce a coma. at this concentration , what is the total mass of alcohol in grams in an adult male whose total blood volume is 5.6L?

Explanation / Answer

Here we have given the concentration of ethyl alcohol 0.065 M,

i.e we know the molarity , from that we can calculate the moles of ethanol present in 5.6 L volume of blood and from moles we can calculate the grams of ethyl alcohol .

Molarity= moles/volume in L,

0.065 =MOLES/5.6 L,

MOLES=0.065*5.6 L,

MOLES=0.364 (MOLES OF ETHYL ALCOHOL),

NOW we can calculate the grams of alcohol present in 5.6 L blood volume.

mass= moles* mol. wt,

mass = 0.364* 46.06,

mass= 16.76 grams of ethyl alcohol
