AI Thread Summary
The discussion focuses on calculating the atom density of 235-U and the molecular density of water in a homogeneous solution containing 10g of 235-U per liter. The conversion of 10g/L to 0.01g/cm^3 is established, with water's density noted as 1g/cm^3. The ratio of atom densities for 235-U and water is derived using the formula N(235)/N(H2O)=density of U*M(H2O)/density of H2O*M(U), resulting in a value of 7.66*10^-4. Participants confirm the calculation of molecular density and emphasize the need to consider the number of atoms in water molecules for accurate atom density. The final atom densities are noted, with 235-U at 2.56E19 and water at 3.35E22, highlighting that water's atom density is significantly higher than that of 235-U.

Homework Statement


homogeneous solution of 235-U and water, contains 10g of 235-U/L of solution, what is the atom density of 235-U and the molecular density of water


Homework Equations





The Attempt at a Solution


first converting 10g/L to 0.01g/cm^3, density of water 1g/cm^3

N(235)/N(H2O)=density of U*M(H2O)/density of H2O*M(U)

N(235)/N(H2O)=7.66*10^-4

i stopped here can anyone giude me

You have calculated the molecular density correctly now calculate the atom density taking into account number of atoms in each water molecule.
 
I calculate it I realize that water atoms density it higher that U235, \U=2.56E19.,/WATER=3.35E22
 
Oh my bad - don't look at my previous post. The last answers you gave are totally correct.

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...
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...
