<h2>Gas Molecules Move in Random Motion </h2>

Explanation:

  • According to the property of an ideal gas the volume occupied by the gas molecules themselves is negligible as compared to the volume occupied by the gas
  • The molecules of ideal gas obey Newton's laws of motion thus they move in random motion
  • According to the above statements we can conclude that Helium gas can fill many more balloons as compared to fit the baloons inside the cylinder because the particles of gas is free to move in random motion and can occupy more volume

Correct way for calculating atomic mass
kolezko [41]

Answer:

mass number = protons + neutrons.

Explanation:

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Korvikt [17]
Moving the electron away from the nucleus requires energy, so the electrons in the outer shell will have more energy than ones in the inner shell. Electrons always have a charge of -1, so the charge in the inner and outer shell will be the same. Therefore the answer is 3

PLS HELP ASAP i really need an answer a correct one
nata0808 [166]

Answer: 67.23 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Putting in the values we get:

\text{Number of moles of methane}=\frac{48g}{16g/mol}=3moles

1 mole of methane occupies = 22.4 L

Thus 3 moles of methane occupy = \frac{22.4}{1}\times 3=67.23L

Thus volume of 48 grams of methane gas is 67.23 L
