If an unknown liquid has a density of 0.756 g/mL and a mass of 2.00 g, what is its volume?
OverLord2011 [107]

Answer:

<h3>The answer is 2.65 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 2 g

density = 0.756 g/mL

So we have

volume =  \frac{2}{0.756}  \\  = 2.645502...

We have the final answer as

<h3>2.65 mL</h3>

Hope this helps you

In the urban areas the population density is very high. Those areas that located in the outskirt of the town are the rural areas.

.Write a short paragraph describing how electronegativity and molecular shape determine the polarity of a molecule. In your para
Yakvenalex [24]

Answer:

See explanation

Explanation:

Electro negativity refers to the ability of an atom in a molecule to attract the shared pair of electrons of a bond closer to itself.

In a molecule, the polarity of bonds is determined by the relative electro negativity of the bonding atoms. If the difference in electro negativity between the atoms in a bond is significant, such a bond is polar in nature e.g H-Cl, H-Br, C-F, etc.

However, the occurrence of polar bonds in a molecule alone does not guarantee the polarity of the molecule. The polarity of a molecule also depends on the shape of the molecule since dipole moment is a vector quantity.

A molecule is polar when the resultant dipole moment which is determined by the shape of the molecule is non zero.

For instance, CO2 contains two polar C-O bonds but the molecule is non polar because the two dipole moments cancel out. Also, symmetrical molecules are nonpolar irrespective of the presence of polar bonds in the molecule.
