Which has greater mass mole of silver or mole of gold?
A mole of gold has a greater mass than a mole of silver because the molar mass of gold (Au) is higher than the molar mass of silver (Ag). The molar mass of gold is approximately 197 g/mol, while the molar mass of silver is approximately 107 g/mol. Therefore, a mole of gold would have a greater mass compared to a mole of silver.
What is the vapor pressure of a water solution in which the molefraction of HgCl2 is 0.163 at 25C?
To calculate the vapor pressure of the water solution with a mole fraction of HgCl2 of 0.163 at 25°C, you would need to use Raoult's Law. The vapor pressure of the solution would be equal to the mole fraction of water multiplied by the vapor pressure of pure water at that temperature. The vapor pressure of HgCl2 can be ignored since its mole fraction is given.
Which has a greater mass.. one mole of silver or one mole of gold?
One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.
How many molecules of water will be present in half mole of water?
6.022 * 10^23 = 1 mole 3.011 * 10^23 = 1/2 a mole
What is the mole ratio of salt to water in NA2SO4.10H2O?
The mole ratio of salt (Na2SO4) to water in Na2SO4.10H2O is 1:10. This means that for every 1 mole of Na2SO4, there are 10 moles of water molecules.
What has the greatest entropy per mole ice water or steam?
Steam has the greatest entropy per mole compared to ice and water, as steam has a higher degree of disorder and randomness in its molecular arrangement.
What is the mass or volume of one mole of water?
The molar mass of water (H2O) is approximately 18.015 grams per mole. The volume of one mole of water at standard temperature and pressure (STP) is about 18.0 milliliters.
Is there a decrease in entropy in COg 3H2g--CH4g H2Og?
In the reaction ( \text{CO}_g + 3\text{H}_2g \rightarrow \text{CH}_4g + \text{H}_2O_g ), entropy typically decreases because there are four moles of gas on the reactant side (1 mole of CO and 3 moles of H₂) and only two moles of gas on the product side (1 mole of CH₄ and 1 mole of H₂O). This reduction in the number of gas molecules generally leads to a decrease in disorder, resulting in lower entropy. However, the overall change in entropy would also depend on factors like temperature and the specific properties of the substances involved.
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 has a greater mass one mole of silver or one mole of gold?
Gold
What is the si units of entropy?
The SI unit of entropy is joules per kelvin (J/K). Entropy is a measure of the disorder or randomness in a system, and it quantifies the amount of energy that is not available to do work.
who will have the greater number of ions 1 mole of nickel or 1 mole of copper?
The number is 6,022140857.10e23.
Does a mole of water weigh the same as a mole of hydrogen?
No. A mole of hydrogen (in its normal form) weighs 2 grams. A mole of water weighs 18 grams.
Which has greater mass mole of silver or mole of gold?
A mole of gold has a greater mass than a mole of silver because the molar mass of gold (Au) is higher than the molar mass of silver (Ag). The molar mass of gold is approximately 197 g/mol, while the molar mass of silver is approximately 107 g/mol. Therefore, a mole of gold would have a greater mass compared to a mole of silver.
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
