AS Practise Chemistry coursework question

AI Thread Summary
The discussion centers on the relationship between mass concentration, molar concentration, and molar mass, with an equation provided: molar mass = mass concentration/molar concentration. The user seeks clarification on how to explain this relationship and whether it connects to the equation for calculating moles. It is noted that while the equations are related, they are not identical, and understanding their differences can be enhanced by writing them with units. The conversation emphasizes the importance of grasping the terminology and concepts involved in these chemistry equations.

Homework Statement



Write an equation in words to show relationship between mass concentration, molar concentration and molar mass and give a short explanation.

Homework Equations



I understand that the equation is:

molar mass = Mass concentration/Molar concentration

The Attempt at a Solution



Where it says 'give a short explanation', what exactly does it want me to say? Does it have something to do with the equation no. moles = Mass/Mr?

I would put the equation in the form

\text{molar concentration} = \frac{\text{mass concentration}}{\text{molar mass}}

in which case it is much more obvious why it is related to the other equation you listed.
 
Thank you very much!

I'm not too good at all this terminology, so could you help me a bit more?

Does rearranging the equation to what you've stated mean that it is the same as the equation no. moles = Mass/Mr? Is this the 'short explanation' the question requires?

Thanks for the help,
Ben.
 
It is not the same but the analogy is obvious. You may try to write both equations with units and see how they differ.

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...
