A level Chemistry relationship between

AI Thread Summary
The relationship between mass concentration, molar concentration, and molar mass can be expressed in words as "mass concentration equals molar concentration multiplied by molar mass." The equation A = M/Mr indicates that A represents mass concentration, M is molar concentration, and Mr is molar mass. To convert mass to moles, the formula is number of moles = number of grams/molar mass. Mass concentration refers to the mass of solute per unit volume of solution, while molar concentration is the number of moles of solute per unit volume. Understanding these concepts is essential for solving problems related to solution concentrations in chemistry.

Not sure :/
This one has popped up a few times, A=M/Mr, but as of this moment I am not sure of what the letters stand for.

The Attempt at a Solution



My Chemistry teacher gave this question as a homework yesterday. After looking through textbooks and my notes I cannot find a word equation involving the mass concentration, molar concentration and molar mass, let alone an explanation for their relationship...

This question was given after a practical session where we attempted to determine the concentration of NaOH from a standard solution of known concentration.

Thank you for any help you can give on this question :smile:

Thread 'Confusion regarding a chemical kinetics problem'

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...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
