Answer: Lead(II) nitrate but idk the rest
Explanation:
Density = mass / volume
mass = density x volume
m = 0.917 x 2.5
m = 2.29 grams
By 1.23 x 1024 you mean 10 to the power of 24 molecules? If so all you need to do is divide the number of molecules you have by Avagadros number, 6.022 x 10^23. This will give you the mols of water, or the mols of anything, since there is always 6.022 x 10^23 molecules in 1 mol of substance.
1.23x10^24 atoms/6.022x10^23 atom/mol = 2.04 mol H20
1 has a higher ionization dismal aoa
