What is the concentration of blood plasma under normal conditions?

AI Thread Summary
The concentration of blood plasma under normal conditions is typically around 55% of total blood volume. Blood plasma is not a single component but a complex mixture primarily consisting of water, proteins, electrolytes, and nutrients. Its main constituents include albumin, globulins, and fibrinogen, contributing to its overall composition. Understanding plasma's molarity involves recognizing its various components and their concentrations. Overall, blood plasma plays a crucial role in transporting substances throughout the body.

what is the concentration of blood plasma under normal conditions??
how do you even begin to answer this question HELP!

This is classed as chemistry? I guess you'd just suppose that plasma is the main constituant in the blood mixture (>90%) and go on to find its molarity from there...but I was under the impression that blood plasma isn't a single component chemical anyway?

And just by a quick google search its usually 55% of blood, and not a single component, so I couldn't give any quick tips?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
