Atom & Molecular Density of 235-U & Water Solution

[matt222]

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.

 

[matt222]

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.
