Answer:
59.76 grams of Li₂O
Explanation:
To solve this problem we will first calculate the moles of Li₂O. One mole of given substance always contains 6.022 × 10²³ particles which can be atoms, ions, molecules or formula units. This number is also called as Avogadro's Number.
The relation between Moles, Number of Particles and Avogadro's Number is given as,
Number of Moles = Number of Particles ÷ 6.022 × 10²³
Putting values,
Number of Moles = 1.204 × 10²⁴ Particles ÷ 6.022 × 10²³
Number of Moles = 2.0 Moles
Secondly, we will convert calculated moles to mass using following relationship.
Moles = Mass / M.Mass
Or,
Mass = Moles × M.Mass
Putting values,
Mass = 2.0 mol × 29.88 g/mol
Mass = 59.76 grams of Li₂O
Answer:
164.088 g/mol

According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure.
According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure. The assumption that matter is made up of microscopic particles that are always in motion forms the foundation of the kinetic-molecular theory, which explains the states of matter.
The observable characteristics and behaviours of solids, liquids, and gases are explained by this theory. The kinetic theory of gases has three primary parts, which are as follows: 1) Neither energy is gained nor lost when molecules collide. 2) In a container, the space occupied by gas molecules is extremely minimal. 3) These molecules move in a straight line at all times.

No two electrons in an atom<span> can have exactly the same </span>quantum<span> numbers. Orbital </span>quantum<span> numbers tell you what energy level the electron is in. In the Bohr</span>model<span>, this represents how high the orbit is above the nucleus; higher orbits have more energy</span>
