The carbon atom is uniquely suited to building large molecules primarily because of its valence electron count of 4 - which means it can bound up to 4 atoms (single bonds) simultaneously. Also, it has a relatively low molecular weight and the best part is that it forms covalent bonds (stable, high energy bonds) with other, non-metallic atoms.

43 mg = [?]g <br>A. 0.043 g <br>B. 4.3 g <br>C. 4300 g <br>D. 43,000 g

Ymorist [56]

Answer:

Option A (0.043 g) is the correct answer.

Explanation:

Given:

= 43 mg

As we know,

$1 \ mg = \frac{1}{1000} \ g$

then,

⇒ $43 \ mg = \frac{43}{1000} \ g$

$= 0.043 \ g$

Thus, the above is the correct alternative.

A Group 2 metal with an electron configuration of [Ne]3s2 combines with fluorine (F2) to

lidiya [134]

The molar mass of the product is equal to 62g/mol.

<h3>Mole calculation</h3>

To calculate the molar mass of a compound it is necessary to have knowledge of the atomic mass of all the elements involved.

In the case of the question, we have the reaction between flourine and magnesium, which represents the element of group 2 with the presented electronic configuration.

Thus, we have the following reaction:

$Mg^{+2} + 2F^{-1} = MgF_2$

So, just add the molar masses, having:

$MM_Mg = 24.3g/mol\\MM_F = 19g/mol$

$24.3 + 19 + 19 = 62.3g$

So, the molar mass of the product, round to the nearest tenth, is equal to 62g/mol.
