Answer:

$\large \boxed{\text{183 g}}$

Explanation:

$\begin{array}{rcl}\text{Density} & = & \dfrac{\text{Mass}}{\text{Volume}}\\\\\rho & = &\dfrac{m}{V}\\\\1.83 \text{ g$\cdot$ cm}^{-3} & = & \dfrac{m}{\text{100 cm}^{3}}\\\\m & = & \text{183 g}\\\end{array}\\\text{There are $\large \boxed{\textbf{183 g}}$ of sulfuric acid.}$

Select all of the below statements that accurately describe the proper Lewis structure for CBr2F2.- The formal charge on each br

Yuri [45]

Answer:

There are 12 lone pairs of electrons on the molecule.

The formal charge on carbon is zero.

There are 4 covalent bonds within the molecule.

Explanation:

The formal charge(FC) can be calculated by the equation:

FC = V - N - B/2, where V is the number of the valence electrons of the neutral element, N is the number of non-bonding valence electrons, and B is the total of electrons shared in bond.

The Lewis structure is represented in the image below. F and Br have 7 valence electrons and C 4 valence electrons.

So, for C, FC = 4 - 0 - 8/2 = 0

For the both Br, FC = 7 - 6 - 2/1 = 0

For the both F, FC = 7 - 6 - 2/1 = 0

For the structure, we can see that there are 12 lone pairs of electrons on the molecule (3 in each Br and 3 in each F).

All the bonds are covalent because the atoms are sharing a pair of electrons, so there are 4 covalent bonds within the molecule.
