Explanation:
The molar mass of a substance is the mass in grams of one mole of the substance.
When dealing with compounds the molar mass is the sum of the of its component atomic masses and expresses in grams per mole;
Given compounds;
Fe₂O₃ and Al₂O₃
Atomic mass;
Fe = 55.845g/mol
Al = 26.9185g/mol
O = 15.9994g/mol
Molar mass of Fe₂O₃ = 2(55.845) + 3 (15.9994) =
111.69 + 47.9982 = 159.7g/mol
Molar mass of Al₂O₃ = 2(26.9185) + 3(15.9994) = 53.837+47.9982
= 101.8g/mol

Answer:
Explanation:
Given
Compound:
Required
Determine the equivalent mass
In the above compound, we have: 2 Al and 3 (O)
The atomic mass of Aluminium is:
The atomic mass of Oxygen is:
So, the equivalent mass is:
Among these two compounds
Lactic Acid is completely soluble in water (1000 g/L) while,
Myristic Acid is insoluble in water [<span>20 mg/L (20 °C)].
Explanation:
Among other factors solubility greatly depends upon the inter-molecular interactions between solute and solvent (
<em><u>LIKE DISSOLVES LIKE</u></em><u>)</u>. Greater the interactions greater is the solubility.
As shown below, Lactic Acid contains two hydroxyl groups and one carbonyl group. These three groups are involved in forming Hydrogen Bond Interactions with the molecules of Water.
Whereas, Myristic Acid contains a long chain of carbon which is non polar in nature. So, due to this non polar carbon chain no such interactions are formed as formed in case of Lactic Acid. Still the less solubility found is due to the interaction of Carboxylic group of Myristic Acid with water molecules, which is comparatively very less.</span>
Answer:saturated
Explanation: they can be mixed together
They are all layers of the atmosphere that exist as separate layers but cooperate with each other. The hydrpsphere is the water part of the atmosphere such as oceans, sea, and lake's. The lithosphere is the under earth action that is happening where such things as faults, and volcanoes occur. The biosphere is where all life exist such as me, you, and animals.
