How is MgSO4 formed?
Magnesium oxide is prepared by igniting magnesium hydroxide (obtained from sea water) or ignition of magnesite ore (consists of MgCO3). The magnesium oxide formed is then reacted with sulfuric acid to produce magnesium sulfate.
What is the valency of MgSO4?
2
Its valency is 2 with a negative charge, which implies this group is in a position to donate electrons as it has an excess of it. On the other hand magnesium is a metal and therefore it is electropositive in nature.
How do you convert mmol to grams?
Add the weight of each atom in the compound: 2 * 55.845 + 3 * 16.000 = 111.69 + 48.00 = 159.69. This is the weight in grams of 1 mole of the compound. 1 millimole Fe2O3 = 159.69 / 1000 = 0.1597 grams = 159.69 milligrams.
What is the Valency of MgSO4?
What is gram molecular weight?
Definition of gram molecular weight : the mass of one mole of a compound equal in grams to the molecular weight. — called also gram-molecule.
How do you find molecular weight from moles?
The formula for this is mass of substance (in grams)molecular weight=number of moles. mass of substance (in grams) molecular weight = number of moles .
How many atoms are in MgSO4?
The chemical formula for magnesium sulfate is MgSO4. A magnesium sulfate molecule is composed of a magnesium atom, a sulfur atom, and four oxygen atoms.
Is MgSO4 ionic or molecular?
Answer and Explanation: Magnesium sulfate is an ionic compound as there is a bond between a metal and a non-metal.
How many valence electrons are in MgSO4?
Magnesium has 2 valence electrons and thus it would rather give those up than get 6 more because it takes less energy; so when it encounters the sulfate ion, it will donate 2 to the oxygen with only four leaving it +2 and the sulfate ion -2. They will then form the ionic compound MgSO4.
How do you calculate molecular weight from mmol?
Calculate the amount of the component in moles using the formula, Amount (in moles) =mass (compound)/molecular mass (compound). In our example, Amount (NaOH)=0.5 g /40 g/mole= 0.0125 moles. Convert moles to millimoles using the following proportion: 1 mole corresponds to 1 millimole x 1,000.
How do you convert molecular weight to grams?
The amount of grams in a mole depends on the substance you have. To work it out, find the atomic or molecular mass of your substance and multiply it by the number of moles you have. For one mole, the atomic or molecular mass will be the same as the weight.
How is gram molecular weight calculated?
How to Find Gram Molecular Mass
- Look up the relative atomic mass of each element in the formula.
- Multiply the subscript after each element symbol (the number of atoms) by that element’s atomic mass.
- Add all of the values together to find the gram molecular mass.
