i just learned this about two weeks ago
Explanation:
Pure Substances cannot be separated easily or, sometimes at all.
I hope this is the answer you were looking for and that it helps!! :)
10 / (7.89) (2)
molarity equation is M = Moles of solute / Liters of solution
7.89 = Moles of solute / 2
(7.89)(2). The question asks for the molar mass which is defined as g/mol. Dividing would give you the unknown compound.
<span>MM = 10g / (7.89)(2)</span>
Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
Answer:
<h2>0.5 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.5 moles</h3>
Hope this helps you
