Answer: 0.8242182 quarts of blood will be present in the brain at rest.
Solution:
According to question: 15% by volume of blood your brain gets at rest
if we are having 5.2 L of blood in our body , then blood present in our brain at rest:

if 1 L= 1.05669 quart
Then 0.78 L will be =0.78 L
1.05669 quart = 0.8242182 quarts
0.8242182 quarts of blood will be present in the brain at rest.
They must have both cations and anions.
I hope this helps.
Answer:
Relation between , molality and temperature is as follows.
T =
It is also known as depression between freezing point where, i is the Van't Hoff factor.
Let us assume that there is 100% dissociation. Hence, the value of i for these given species will be as follows.
i for = 3
i for glucose = 1
i for NaCl = 2
Depression in freezing point will have a negative sign. Therefore, d
depression in freezing point for the given species is as follows.
=
=
=
Therefore, we can conclude that given species are arranged according to their freezing point depression with the least depression first as follows.
Glucose < NaCl <
