How is equivalent mass calculated?

To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.

What is equivalent weight of caso4?

Answer Expert Verified = 136u. Hope my answer is helpful to you.

What is the mass of equivalent?

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 n factor of MgCl2?

Cl has a valency of 1. The compound thus formed becomes MgCl2. n-factor of MgCl2 = total positive charge = total negative charge = 2.

What is the equivalent mass of KMnO4?

Equivalent mass of KMnO4 in acidic and alkaline medium is 31.6 and 52.7 respectively.

What is the equivalent mass of sulphuric acid?

Sulphuric acid contains two replaceable hydrogen. Hence, the equivalent weight of sulphuric acid is 49u.

What is the equivalent weight of cacl2?

Answer:Therefore 55 grams of calcium chloride is the equivalent weigh because 55 grams of calcium chloride would supply one mole of positive or negative charges when dissolved in water.

What is the N factor of alcl3?

Aluminium chloride (AlCl3), also known as aluminium trichloride, describe compounds with the formula AlCl3(H2O)n (n = 0 or 6).

Is MgCl2 acidic or basic?

Magnesium chloride is slightly acidic because it is formed by the reaction of a relatively weak base. Thus MgCl2 is slightly acidic in nature.

What is equivalent mass of oxalic acid?

Equivalent mass of oxalic acid = molecular mass of oxalic acid/2 = 126g/2 = 63 grams. Therefore, the equivalent weight of oxalic acid is 63 grams.

What is equivalent weight of n2h4?

Equivalent weight = 32/2 = 16 (due to presence of two lone pairs its acidity is 2.)

How many grams are in mole of MgCl2?

1 mole is equal to 1 moles MgCl2, or 95.211 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles MgCl2 and gram. Type in your own numbers in the form to convert the units!

What is the melting point of MgCl2?

The melting point of the chemical compound magnesium chloride is 1,317 Fahrenheit

What is the molecular weight for MgCl2?

Also, MgCl2 molecular weight is 95.210 g/mol. Magnesium chloride predominantly exists as various hydrates, hexahydrate particularly MgCl2 *6H2O which is having the molecular weight of 203.301 g/mol. Occurs as a natural mineral Bischofite, magnesium chloride hexadyrate named after a german geologist Karl Gustav Bischo.

What is the formula mass of magnesium chloride MgCl2?

The formula of magnesium chloride is MgCl2. The molar mass of MgCl2 is (24.30 + 2 × 35.45) g/mol=95.20 g/mol.
