1 Mole of magnesium = 24.305 grams
The 24.305 comes from the Periodic Table of elements. Simply find Mg and the Atomic Mass (the biggest number) is the same if u have 1 mole of that.
So 24.305 grams x 4 = 97.22 grams

∙ 12y agoAnswer: 97.22g
explanation: We know from the periodic table that the molecular weight (formula weight) of Magnesium (Mg) is 23.305g/mol. We multiply 4mol x 23.305g/mol so that the moles will cancel each other out and are left with 97.22g.

The mass of one mole (or molar mass) of magnesium chloride is 95.205g/mol. Multiply the molar mass of magnesium chloride times 4.30mol, which gives 409.3815g of magnesium chloride. Since 4.30 has three significant figures, round 409.3815g to 409g magnesium chloride.
4.30mol MgCl2 x 95.205g MgCl2/mol = 409.3815g MgCl2 (round to 409g MgCl2 due to significant figures)

∙ 10y agoTo convert millimoles to milligrams, you have to multiply by the molecular weight. The molecular weight of magnesium is 24.3 g/mol. Therefore 4 x 24.3 is 97.2 milligrams.

How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen Here is the formula 2 Mg plus O 2 is equal to 2 Mg O?
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
What is the percentage of elemental magnesium in magnesium stearate?
Magnesium stearate is composed of approximately 6-8% magnesium. The rest of the compound is made up of stearic acid, which accounts for the remaining 92-94% of the substance.
What is the suger range in human body?
The body maintains the blood glucose level between about 3.6 and 5.8 mM (mmol/L, i.e., millimoles/liter), or 64.8 and 104.4 mg/dL. normal blood glucose level in humans is about 4 mM (4 mmol/L or 72 mg/dL, i.e. ~issa~
How 2 moles of Magnesium oxide are formed when 4 moles of Mg reacts with O?
2Mg + O2 -----> 2MgO So two moles of magnesium oxide are formed if x moles of magnesium are allowed to react with only 1 mole of oxygen molecules. The oxygen has become the limiting ingredient.
How can you get crystals from the reaction of magnesium and sulphuric acid?
To obtain crystals from the reaction of magnesium and sulfuric acid, you can follow these steps: 1) Mix magnesium ribbon with diluted sulfuric acid in a beaker. 2) Allow the reaction to occur, which will produce hydrogen gas and magnesium sulfate. 3) Filter the mixture to remove any excess magnesium or impurities. 4) Evaporate the filtered solution to allow the magnesium sulfate to crystallize and form crystals.

Does magnesium react with nitric acid?
Yes, forming the salt Magnesium nitrate and hydrogen gas. The reaction forms Magnesium Nitrate and hydrogen gas Mg + 2HNO3 --> Mg(NO3)2 + H2 Heating magnesium nitrate hexahydrate decomposes it into magnesium oxide, oxygen, and nitrogen oxides. 2 Mg(NO3)2 → 2 MgO + 4 NO2 + O2
What are the elements in magnesium sulfate?
Magnesium sulfate has elements magnesium, sulfur, and oxygen in it. Its chemical formula is MgSO4, meaning that it will have one magnesium atom, one sulfur atom, and four oxygen atoms (all electrically charged to result in an electrically neutral molecule). This compound is also called epsomite and is commonly used in Epsom Salt. This compound has many other applications, especially in the medical field, other than this.
What is the oxidation number of magnesium carbonate?
+2 for Mg, +4 for C, -2 for each O in MgCO3
HOW MUCH IS 4 grams into mg?
4000 mg
What is the percentage of elemental magnesium in magnesium stearate?
Magnesium stearate is composed of approximately 6-8% magnesium. The rest of the compound is made up of stearic acid, which accounts for the remaining 92-94% of the substance.
How are potassium (K) magnesium (Mg) and vanadium (V) similar?
Potassium and vanadium are in the period 4 of the periodic table.
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
What are the elements present in magnesium phosphate?
Magnesium phosphate has the formula 'Mg3(PO4)2'. Hence the elements are Mg (Magnesium x 3) P (Phosphorus x 2) O (Oxygren 4 x 2 = 8).
What is the suger range in human body?
The body maintains the blood glucose level between about 3.6 and 5.8 mM (mmol/L, i.e., millimoles/liter), or 64.8 and 104.4 mg/dL. normal blood glucose level in humans is about 4 mM (4 mmol/L or 72 mg/dL, i.e. ~issa~
What is the formula of Magnesium dihydrogen phosphate?
dihydrogen phosphate --> PO4(-3) + 2H --> H2PO4(-1) magnesium dihydrogen phosphate --> Mg(2) + H2PO4(-1) --> Mg(H2PO4)2
Calculate the Mass of magnesium sulphate that would be obtained from 4 grams of magnesium?
Masses: Mg= 24, S= 32, O= 16 Magnesium = 24g Magnesium sulphate = (24+32)+(16x4) = 120g. Therefor we know: 24g of Mg ----> makes 120g of MgSO4. To get to 4g from 24g, you devide by 6. (24 devided by 6 = 4g) And to find what it would make, you devide 120 by 6 too. Which = 20g. 4g of Mg ----> 20g of MgSO4.
