What is the molar concentration of ammonia in a #35%# #w/w# solution for which #rho_"solution"=0.88*g*mL^-1#?
We can address the number of ammonia molecules in conc. ammonia.........
Concentrated ammonia is an aqueous solution of ammonia in water. Pure ammonia is a room temperature gas.
At room temperature, the density of a saturated solution in water is
And we can thus work out its concentration in
And thus in
Of course in this solution there are still a lot more water molecules, each of which contributes one oxygen atom, and 2 hydrogen atoms.
