At 100 degrees Celsius (or 373.15 K), the average kinetic energy of one mole of an ideal gas can be calculated using the formula ( \text{KE} = \frac{3}{2}RT ), where ( R ) is the universal gas constant (approximately 8.314 J/(mol·K)). Plugging in the values, the average energy is about ( \frac{3}{2} \times 8.314 , \text{J/(mol·K)} \times 373.15 , \text{K} ), which yields approximately 4,155 J per mole.
What else can I help you with?
If you have a balloon filled with one mole of gas at zero degrees Celsius at a pressure of one atmosphere how many gas particles do you have?
At standard temperature and pressure (0 degrees Celsius and 1 atmosphere), one mole of any ideal gas contains approximately 6.022 x 10²³ particles, which is known as Avogadro's number. Therefore, if you have a balloon filled with one mole of gas at these conditions, you have about 6.022 x 10²³ gas particles in that balloon.
What is the Celsius temperature of 1 mole of a gas that has an average kinetic energy of 3866 joules?
To find the Celsius temperature of a gas with an average kinetic energy of 3866 joules, we can use the formula for the average kinetic energy of a gas, which is ( KE = \frac{3}{2} nRT ). For 1 mole of gas (n = 1), this simplifies to ( KE = \frac{3}{2} RT ). Rearranging for temperature (T) gives ( T = \frac{2 \times KE}{3R} ). Using the gas constant ( R \approx 8.314 , J/(mol \cdot K) ), we find ( T \approx \frac{2 \times 3866}{3 \times 8.314} \approx 310.5 , K ). Converting this to Celsius gives ( T_{C} \approx 310.5 - 273.15 \approx 37.4 , °C ).

How can you calculate the vapour pressure of water over the solution at 90 degrees Celsius vapour pressure of water at 90 degrees Celsius is 525.8mmHg?
You can use Raoult's law to calculate the vapor pressure of water over the solution. The formula is P_solution = X_solvent * P°_solvent, where P_solution is the vapor pressure of the solution, X_solvent is the mole fraction of the solvent (water in this case), and P°_solvent is the vapor pressure of pure water at 90 degrees Celsius (525.8 mmHg). Calculate the mole fraction of water in the solution and then use it in the formula to find the vapor pressure.
Compared to the average kinetic energy of 1 mole of water at 0 degree Celsius the average of kinetic energy of 1 more of water is 298 K is?
The average kinetic energy of 1 mole of water at 0 degrees Celsius is the same as at 298 K because temperature is a measure of average kinetic energy per molecule; it doesn't depend on the amount of substance. Therefore, the average kinetic energy remains constant for 1 mole of water.
What is the average kinetic energy of 1 mole of a gas that is at 0 degrees Celsius?
The average kinetic energy of a gas can be calculated using the formula KE = (3/2)RT, where R is the gas constant and T is the temperature in Kelvin. At 0 degrees Celsius, the temperature in Kelvin is 273 K. For 1 mole of gas, substituting these values into the formula gives an average kinetic energy of around 3/2 * 8.314 J/mol*K * 273 K.

How many kilocalories of energy is released when one mole of fat is oxidized?
On average, one mole of fat releases around 9 kcal of energy when fully oxidized.
How much Would the freezing point of water decrease of sugar were added to 1 kg of water?
The freezing point of water decreases by about 1.86 degrees Celsius for each mole of solute (such as sugar) dissolved in 1 kg of water. So, the freezing point would decrease by 1.86 degrees Celsius for every mole of sugar added.
What is the melting point of biphenyl?
the melting point of biphenyl is 70 degrees Celsius.
What is the average kinetic energy of all the molecules in an object?
Average KE for molecules is defined by (3/2)RT: where R is the ideal gas constant (8.314 J K-1 mol-1 ) and T is the absolute temperature of the fluid (gas/liquid) in Kelvin. The reason for 3/2 is based on the x,y, and z planes that the gas molecules could be moving (vibrating, translating, rotating). For just a single plane it would be 1/2RT. The KE derived from the equation is the average KE for a mole of gas molecules and not the energy of every, or any of the molecules. A single gas molecules chosen at random may have any KE associated with it, but this equation gives the average of all molecules

Lithium fluoride has the molecular formula of LiF. LiF has a molecular weight of 25.94 grams per mole and melting point of 845 degrees Celsius.
Calculate the mass of propylene glycol that must be added to 0.340 kg of water to reduce the vapor pressure by 2.88 ATM at 40 degrees Celsius at 40 degrees Celsius equals 55.3torr?
To calculate the mass of propylene glycol needed, we can use Raoult's law. Given that the vapor pressure of pure water at 40 degrees Celsius is 55.3 torr and the desired vapor pressure when mixed is 2.88 atm, we can calculate the mole fraction of propylene glycol needed. From this, we can find the mass of propylene glycol required to achieve this mole fraction when combined with 0.34 kg of water.
