The number of moles of the gas is 0.0396 moles.

<h3>What is the ideal gas equation?</h3>

The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.


Thus;

Volume = 1000.0 cm 3 or 1 L

Gas constant = 0.082 atmLK-1Mol-1

Temperature = 32 o C + 273 K = 305 K

Pressure =  752 mm Hg  or 0.99 atm

Thus;

PV = nRT

n = PV/RT

n =  0.99 atm *  1 L/0.082 atmLK-1Mol-1 * 305 K

n = 0.0396 moles

Organic molecules are defined as chemical compounds that contain ______ in distinct ratios and structures.
OLga [1]

Answer:

The answer is: <em>carbon</em>

Explanation:

Organic molecules contain the chemical element carbon (C) in its structure. In this type of molecules, carbon is usually bonded to hydrogen (H), oxygen (O) and, with less frecuency, nitrogen (N). Therefore, in these molecules, carbon forms simple, double and triple bonds with itself. Examples of organic molecules that are very important in biology are carbohydrates, lipids, proteins and nucleic acids.

NEED HELP PLEASE!!!!
Feliz [49]
I think the correct answer would be the third option. The reason I2 has a higher melting point than F2 is because I2 possesses a more polarizable electron cloud. I2 contains more electrons than F2 which would result to a stronger intermolecular forces. Having stronger intermoleculer forces would mean more energy is needed to break the bonds so a higher melting point would be observed.
