Why is the molar specific heat of diatomic gas larger than that of a monoatomic gas?
Diatomic gases have more degrees of freedom. They are also larger in size and mass. specific heat is proportional to the number of degrees of freedom; monatomic gases can only move linearly and have 3 degrees of freedom, molecules can also rotate and vibrate, so have more degrees of freedom.

What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
Why is the molar specific heat of the diatomic gas usually larger than that of mono-atomic gas?
A monatomic gas has no contribution from vibration to its specific heat. A diatomic gas has both vibration of the two atoms as the stretch and compress the bond between them and can rotate faster or slower. With more ways to store energy than just translational energy, diatomic gases tend to have higher heat capacities.
What is the weight in grams of 3 moles of diatomic oxygen?
One mole of oxygen molecule weighs 32g. Therefore, 3 moles weigh 32 x 3= 96g
What is the molar mass of Casey rounded to the nearest gram?
To determine the molar mass of "Casey," we first need to clarify that "Casey" does not refer to a specific chemical compound or element with a defined molar mass. If "Casey" refers to a substance or a mixture, please provide its chemical formula or composition for accurate calculation. Otherwise, without specific information, it's impossible to provide a molar mass.
What is the molar weight of petroleum ether?
petrolium ether is a mixture of pentane and hexane so has no molar mass

Why does a diatomic gas have greater energy content per mole than monoatomic gas at the same temperature?
The molar specific heat of a diatomic molecule is CV = (5/2) R, meaning U = (5/2) n R T, while, for a monatomic gas, CV = (3/2) R or U = (3/2) n R T. Since the molar specific heat is greater for a diatomic molecule, there is more internal energy stored inthe motion of the molecules for the same temperature than for that temperature in a monatomic gas.
What is the molar mass of oxygen gas?

What is 42 grams of diatomic oxygen in moles?
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
What is the mass of 1 Mole of diatomic nitrogen gas?
The molar mass of diatomic nitrogen (N2) is approximately 28.02 g/mol. Therefore, the mass of one mole of diatomic nitrogen gas is 28.02 grams.
What element forms a diatomic gas with a mass of 160 amu?
Bromine (Br) has a molar mass of 79.904 amu (atomic mass units), which is extremely close to 80. Bromine is diatomic so when two bromine molecules are put together to create a diatomic gas, the molar masses of each bromine add to get a combined molar mass of 160 amu.
When finding the moles of a gram sample of a diatomic element do you divide by twice the molar mass?
YE you do divide by 2
Where on your body will you find a' molar'?
A molar is one of your larger rearmost teeth found inside your mouth.
Why you prefer molar specific heat as compared to the simple specific heat?
In chemistry instead mass in kg it would be nice to deal the quantity in moles. Hence molar specific heat is best fit.
What element is larger H2o or MgSO4?
Neither H2O nor MgSO4 are elements. They are COMPOUNDS. In terms of volume occupied , MgSO4 is the larger.
What is the molar specific heat of all metals near room temperature?
The molar specific heat of most metals near room temperature is approximately 25 J/molK.
