1. Find the molar mass (MM) of the substances.MM FeSO4 = 151.91g+MM 7H2O = 126.11gMM FeSO4 x 7H2O = 278.02g2. Find the percent water of hydrate.Divide the mass of water by the mass of the hydrate; multiply result by 100%.126.11g278.02g x 100%Percent water of FeSO4 * 7H2O is 45.36%.Finding Molar Mass# atoms Element A x atomic mass Element A = Mass A# atoms Element B x atomic mass Element B = Mass B... etc.Add up all the mass values for the substance and you have the molar mass of the substance.
7h2o
Oxygen is a chemical element with the symbol O and atomic number of 8. Its percentage composition in the compound NiSO4 x 7H2O is 31.3%.
-Ammonia is NH3 -Vinegar is CH3COOH - and you think it would be C2H4O2 but it's NOT!!! -Baking Soda is NaHCO3 -Milk I'm pretty sure is a mixture, so you will have to find the chemical equation, not formula. -I don't think that magnesia is an actual thing, but MAGNESIUM is Mg. -Epsom salts are MgSO4 + 7H2O
Mg2+
MGS04 7H2O is Magnesium Sulfate . It is a heptahydrate. Epsom Salts
The chemical equation for the dehydration of magnesium sulfate (MgSO4) is as follows: MgSO4·7H2O + Heat => MgSO4 + 7H2O A link is provided below for more information.
MgSO47(H2O) ------> MgSO4 + 7H2O MgSO4 ----------MgO + SO3 heat is added.
Pi r2
Yes its aqueous solution is acidic in nature due to hydrolysis of salt.
Eposm salt, or Magnesium sulfate, has the chemical formula MgSO4·7H2O
MgSO4∙7H2O(s) -heat→ MgSO4∙H2O(s) + 6H2O(g)
The formula for Magnesium hydrogen sulfate is: Mg(HSO4)2
62.816
Epsom salt is magnesium sulfate (MgSO4·7H2O), table salt is sodium chloride (NaCl).
48.8 g MgSO4 & 51.2 g H2O Convert the mass into moles by dividing molar mass for each. Then obtain a ratio of moles of water over moles of Magnesium Sulfate, and you would get 7. MgSO4 . 7H2O would read as Magnesium Sulfate Heptahydrate.
