- 1 mole of water molecules means 6.022×1023 water molecules. 5. Conclusion: In summary, a mole is a unit that allows chemists to count quantities of atoms and molecules in a manageable way, using Avogadro's constant to relate the number of particles to the amount of substance. Show More...
For the mole fraction of water in the KCl solution, it is equal to the moles of water over the sum of the moles of water and moles of KCl solution. The given concentration is expressed in molality which suggests that 1 kilogram of solvent (which is water) is used to prepare ...
What is the molar heat capacity of water?Molar heat capacityThe molar heat capacity is the amount of energy which is required to raise the temperature of one mole of a substance by one degree and its SI unit is J/mol.Answer and Explanation: ...
The pH of water can vary from $ 0 $ and $ 14 $ , when the pH of a substance is above $ 7 $ , it is a basic substance. When the pH is below $ 7 $ , it is an acidic substance. The pH is a logarithmic factor, when a solution becomes ...
Calculate the number of aluminium ions present in 0.051 g of aluminium oxide. (Hint: The mass of an ion is the same as that of an atom of the same element. Atomic mass of Al = 27 u) View Solution What is the mass of 0.5 mole of water (H2O). (Atomic masses : H=1u,O=16...
Capybaras live naturally in parts of South and Central America that have access to fresh water bodies. This includes countries such as Argentina and Panama. Is a capybara a rat? No. While the capybara and rat are both rodents, a capybara is different from a rat. Capybaras are large, semi...
What is the mass of 1 mole of a raindrop? Mole: The Mole is a unit that represents a certain number. It is defined as the number of carbon atoms contained in a pure sample carbon-12 of mass12g. The constant number of called the Avogadro's constant. The order of the magnitude of ...

1 mole of water is heated by 1C°. The increased thermal energy makes additional microstates accessible. (The increase is by a factor of about 1020,000,000,000,000, 000,000,000.) Equal volumes of two gases are allowed to mix. The effect is the same as allowing each gas to expand to...
