What are the units of b? For water the numerical value of a is 5.464 and the numerical value of b is 0.0305. atm Use the van der Waals equation to calculate the pressure of a sample of water at 520.0 °C with a molar volume of 0.183 L/mol. Round your answer to the correct number of significant digits. Use the Ideal Gas Law to calculate the pressure of the same sample under the same conditions. Round your answer to the correct number of significant digits. atm

a has units of . The factor - nb accounts for the volume occupied by the gas molecules. b has units of L/mol.

Explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
