What volume is a mole of water?
The volume of one mole of water at 277 K is 18 ml.
What is the value of 2 moles of water?
One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.
What is the mass of 2 moles of water molecules?
If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.
What is the volume occupied by 1 mole of liquid water?
Explanation: One mole of liquid water is equal to to 18 grams of water. According to the density of water at normal temperature pressure the value 1gram per centimetre cube. hence the volume which is occupied by 18 grams of water will be equal to 18 cm ³ or 18 ml.
What is the volume formula?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the mass of 2 moles of CO2?
The answer is 24 g.
How many molecules are there in 2 moles of H2O?
Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.
How do you find pressure from volume?
Depending on which parameter we want to estimate, Boyle’s law formula can be written in various ways. Let’s say we change the volume of a gas under isothermal conditions, and we want to find the resulting pressure. Then, the equation of Boyle’s law states that: p₂ = p₁ * V₁ / V₂ or p₂ / p₁ = V₁ / V₂ .
How do you find the volume of a mole of gas?
STP is the standard conditions of Temperature and Pressure, where, T=273K and P=1atm . Since we are looking for the volume of one mole, then n=1mol . The volume of one mole of a gas is either 22.414 L , or 22.711 L , depending on the pressure used for STP .
