AI Thread Summary
The discussion revolves around determining the mass percentage composition of a mixture of naphthalene and anthracene dissolved in benzene. Participants clarify that the question requires finding the individual mass percentages of naphthalene and anthracene within the original 1.60 g sample, rather than a simple ratio of the total mass. The freezing point depression method is suggested for calculating the individual masses based on the provided freezing point data and the freezing point constant of benzene. The importance of distinguishing between total mass composition and individual component percentages is emphasized. Accurate calculations will yield the specific mass percentages of naphthalene and anthracene in the mixture.

Homework Statement


"A 1.60 g sample of a mixture of naphtalene, C10H8. and anthracene, c14H10 is dissolveed in 20.0g of benzene, C6H6. The freezing point of the solution is 2.81C. Pure Benzene freezes at 5.51C and has a Kf = 5.12C kg/mol. Determine the composition (mass percentage) of naphthalene-anthracene mixture?"

my question is are they asking us for the easy mass composition of the Nap. and ant. mixture over the total mass or are they asking me to find the actual mass % between nap and ant., as in how many grams out of the 1.6 is the mass of nap?

Homework Equations





The Attempt at a Solution


if the question is as easy as it seems:
1.6/21.6 = 7.4%

No, they ask about % composition of the original mixture - how many percent of naphtalene, how many perecent of anthracene.

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...
