Eva8 [605]3 years ago

To determine the molar mass, you need to get the atomic mass of the molecule. To do this, check the periodic table for the atomic mass or average atomic weight of each element.

Mg = 24.305 x 1 = 24.305 amu

O = 15.9994 x 2 =31.9988 amu

H = 1.0079 x 2 = 2.0158 amu

 

Then, add all the components to get the atomic mass of the molecule.

24.305 amu + 31.9988 amu + 2.0158 amu = 58.3196 amu


The atomic mass is just equivalent to its molar mass.

So, the molar mass of Magnesium hydroxide (Mg(OH)2) is 58.3196 g/mol.

Answer:
molar mass of Mg(OH)2 = 58.305 grams/mole

Explanation:
From the periodic table:
atomic mass of Mg = 24.305 grams
atomic mass of oxygen = 16 grams
atomic mass of hydrogen = 1 gram

Now the given compound has:
1 mole of Mg, 2 moles of oxygen and 2 moles of hydrogen
Therefore:
molar mass of Mg(OH)2 = 24.305 + 2(16) + 2(1) = 58.305 grams/mole

How are the properties of high-tech ceramics the same as those of traditional clay ceramics, and how are they different? Refer t
algol13

Modern ceramics have all properties which have traditional ceramics for example hardness, high resistance to chemicals, and heat and they are different from traditional ceramic because have superior magnetic are or electrical properties.

One example is classical ceramic which is an insulator but when is dopped with ZnO it becomes a good conductor at high voltages.

What is the net amount of energy released when one mole of h2o(?) is produced?
german
The net amount of energy produced can be obtained from a table of enthalpy change of formation, available online.

The enthalpy change of formation indicate how much energy the 1 mole of the product (H2O) has relative to the elemental reactants (H2 and O2).  In other words, the "lost" energy equals the heat/energy released. 

For water (H2O), this value is -285.8 if the final product is a liquid under standard conditions, and -241.82 if the product is in gas form which contains some energy that could be further released.  This means that if the final product (H2O) is in liquid form, energy released is 285.8 kJ/mol.

Since water is in liquid form under standard conditions, the first value (285.8 kJ/mol) is generally appropriate.
