How could you establish the formula of $ZnSO_4*7H_2O$?
Possibly, the best means would be by complexometry. So, perhaps you would take thesalt, $ZnSO_4*7H_2O$, or one of its several hydrates, and perform a titration with $"EDTA"$................. And $"EDTA"$ reacts...

What is the net ionic equation of the reaction of $MgSO_4$ with $Ba(NO_3 )_2$?
And so we gots.... $Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr$ ...as the net ionic equation. The magnesium and nitrate ions are along for the ride.....and stay in solution. The complete metathesis...

A chemist heats 100.0 g of $FeSO_4 * 7H_2O$ n a crucible to drive off the water. If all the water is driven off, what is the mass of the remaining salt?
$54.64$ $"g"$ anhydrate With $"100.0 g"$ of the heptahydrate, use the molar mass to determine how many mols you have. Mols are interconvertible, as one mol...

How many oxygen atoms are represented by $MgSO_4 * 7H_2O$?
In $"MgSO"_4$, the number of oxygen atoms is represented by the subscript directly next to the $"O"$. In $"7H"_2"O"$, the coefficient $7$ can be multiplied throughout each element in the...

An unknown compound has the formula $C_xH_yO_z$. You burn 0.1523 g of the compound and isolate 0.3718 g of $CO_2$ and 0.1522 g of $H_2O$. What is the empirical formula of the compound?
First, work out the mass of each element that was present in the original compound. Carbon is always present as $CO_2$ in the ratio (12.011 g / 44.0098 g), and...

4.6g of an organic gaseous compound was burned. Its gas density compared to air is 23. After burning this compound, 4.48 L of CO2 (at 0 °C and 1 atm) and 5.4 g of H2O were produced. What is the name and chemical formula of this organic compound?
If we assume that the (23) of the gas has been compared to the density of $H_2$,then the molar mass of the gas becomes $46"g/mol"$ The organic compound burnt...

How many grams of $MgSO_4$ are needed to prepare 125mL 0.200M magnesium sulfate?
And $"mass of solute "=" moles"xx"molar mass"$ And so we calculate the product: $"Volume"xx"Concentration"xx"Molar mass of magnesium sulfate"$ $=125xx10^-3cancel(L)xx0.200*cancel(mol*L^-1)xx120.37*g*cancel(mol^-1)$, an answer with units of mass as required. $=??*g$

What molar quantity of magnesium ion is present in a $1000*mL$ volume of $0.50*mol*L^-1$ $MgSO_4(aq)$?
You specify a $0.5*mol*L^-1$ solution of $MgSO_4(aq)$. Since $"Concentration"$ $=$ $"Moles of solute"/"Volume of solution"$, $"Moles of solute"="Concentration"xx"Volume of solution"$. If we have a $1000*mL$ volume, then....... $"Moles of...
