Answer:
95.2 g/mol
Explanation:
To calculate the molar mass of MgCl2
We have to separately see the molar masses of Magnesium and Chlorine
Molar mass of Magnesium: 24.305 g/mol
Molar mass of Chlorine: 35.453 g/mol
As there are two atoms of chlorine in the said molecule so the molar mass of chlorine will be multiplied by 2.
35.453*2 = 70.906 g/mol
So the total molar mass of the said molecule = Molar mass of Mg + Molar mass of two atoms of chlorine
= 24.305 + 70.906
=95.211 g/mol
Rounding off to .1
95.2 g/mol
<u>Answer:</u> The correct statement is an ionic bond will form because electrons are transferred.
<u>Explanation:</u>
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.
A covalent bond is formed when there is sharing of electrons between the elements forming the bond. This bond is formed between two non-metals.
Hence, the correct statement is an ionic bond will form because electrons are transferred.
Answer: 63.6 u
Explanation:
RAM = RAM of isotope-1 X (% abundance) + RAM of isotope-2 X (% abundance) ÷ 100
63 X 70% + 65 X 30% ÷ 100 = 63.6 u
