What do you mean by equivalent weight of magnesium is 12?
ANS : The equivalent mass of Mg is 12 means: i) 12 P/m of magnesium displaces 1.008 P/m of hydrogen from dilute acid. ii) 12 P/m of magnesium combines with 8 P/m of oxygen and 35.5 P/m of chlorine.
How do you calculate equivalent weight?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
How is CA equivalent weight calculated?
The equivalent weight of any substance can be calculated as the ratio of its molecular or atomic weight to the valency it possesses. It has the unit as mass specifically amu. Atomic number of Calcium is 20. Thus, it has 2 valence electrons as stated by Bohr’s electronic configuration i.e. 2, 8, 8, 2.
What is the equivalent weight of mgso4?

Is equivalent weight and equivalent mass same?
Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
What is normality and equivalent weight?
What is Normality? Normality refers to the gram equivalent of the substance being dissolved in one liter of the solution. Gram equivalent weight can be defined as the molecule’s reactive capacity. It is measured as ‘N’,eq/L or meq/L where ‘eq’ stands for equivalents while ‘meq’ stands for milliequivalent.
What is the equivalent weight of Ca in CaCO3?
Equivalent mass of Ca in CaCO3 = 50g. Explanation: The equivalent mass of CaCO3 is 100g/2=50g. Thus,The equivalent mass of Calcium Carbonate is 50g.
What is CaCO3 equivalent weight?
= 40 + 12 + 48. = 100. The molecular weight of the calcium carbonate is 100. ∴ The equivalent weight of the calcium carbonate is = 100/2 = 50.
Is magnesium sulfate the same as magnesium?
Magnesium sulfate is the form of magnesium in Epsom salts. Many people add Epsom salts to baths and foot soaks to soothe aching muscles. However, there is little high quality evidence showing that the body can absorb much magnesium from magnesium sulfate baths.
What is the equivalent weight of znso4?
= molar mass/ 2. = 65.38 + 32 + 4 × 16 + 7 × 18 / 2. = 287.38 /2 = 143.69 g.
What is its equivalent weight mass?
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 g / 2 = 8.0 g.
How do I calculate equivalent weight?
Calculate the molecular weight of the substance Multiply the atomic weight by the element’s subscript in the molecular formula and add. In hydrates, multiply the weight of the water molecule by the number located between the dot and the H2O and add to the total.
What is the best magnesium for weight loss?
Best magnesium for weight loss is ReMag, pico-ionic stabilized mineral formula. ReMag absorbed at the cellular level and 100 percent. The rest of the magnesium supplements consumed from four to 50 percent. ReMag consists of stabilized magnesium ions.
How many MEQ in 1 gram of magnesium?
Exists as magnesium sulfate heptahydrate – MgSO4.7H2O MW =246.47 Calculations: (1gram MgSO4 (2ml of 50% soln)/246.47) x 1000= 4.057 or ~ 4.06 mmol x valence (2) = 8.12 meq. (contains 10% elemental magnesium)
Can magnesium help me lose weight?
While magnesium may help improve insulin and blood sugar levels, supplementation alone may not promote weight loss. Magnesium may not help you lose excess fat, but it may help prevent the weight gain and bloating associated with premenstrual syndrome.
