When you have 3.86 g of CuSO4 - 5H2O how many total moles of ions are released when each of the following samples dissolves completely in water?

CuSO4.5H2O
mass 3.86 g
molar mass: 249.70 g/mol
3.86 g / 249.70 g/mol = 1.546*10-2 mol CuSO4.
Each mole CuSO4.5H2O will dissociate in 1 mole Cu2+ and 1 mole SO42-, giving total of 2 moles ions.
So 1.546*10-2 mol CuSO4 * 2 = 3.09*10-2 mole ions

When you have 8.66 x 1020 formula units of NiCl2 how many total moles of ions are released when each what samples dissolves completely in water?
8.66 x 10^20 formula units NiCl2 x (1 mol NiCl2 / 6.022x10^23 # atoms NiCl2) x (3 mol Ni and Cl2 / 1 mol NiCl2) = 4.31 x 10^-3 moles of ions

Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
When you have 0.43 mol of NH4Cl how many total moles of ions are released when each of the following samples dissolves completely in water Show work so I can understand how to do it on my own?
Basically you have 0.43 mol of NH4Cl. In NH4Cl there are two ions, NH+ and Cl-. You set up the problem as: 0.43 mol of NH4Cl X (2 mol ions/ 1 mol of NH4Cl) = 0.86 mol ions
Which of the samples dissolved partially not completely?
what is the appearance of the mixture
We were sent following samples through TNT on 01.04 this sentence is correct or not?
Better to say: We were sent the following samples through TNT on ..................(the date should be clear, 01.04 isn't very clear). After this sentence there would be a list of the 'samples'.
If two samples of matter had completely identical sets of properties what important inference could be made about the two samples?
Nova net answer: They are the same
When you have 8.66 x 1020 formula units of NiCl2 how many total moles of ions are released when each what samples dissolves completely in water?
8.66 x 10^20 formula units NiCl2 x (1 mol NiCl2 / 6.022x10^23 # atoms NiCl2) x (3 mol Ni and Cl2 / 1 mol NiCl2) = 4.31 x 10^-3 moles of ions

What conditions are necessary in order to use a test to test the differences between two population means?
The samples must be randomly selected, independent, and normally distributed. The following are necessary to use a t-test for small independent samples. 1. The samples must be randomly selected. 2. The samples must be independent. 3. Each population must have a normal distribution.

samples of them
What are the binary colliodal samples?
A colloid is a suspension of one of more chemical species in others in which none dissolves in the others. If only two species are involved then the colloid is said to be binary. A portion of such a mixture is said to be a sample of it.
