Argon gas has a boiling point of -197 °C. Which of the following diagrams best represents the
Paha777 [63]

Answer:

(a)

Explanation:

Hello,

In this case, the temperature required to boil argon, it means, transform it from liquid to gas is -197 °C. In such a way, since the temperature inside the steel sphere is -190 °C, which is greater than the boiling point, we realize argon is gaseous, therefore, the molecules will be spread inside the sphere as they will be moving based on the kinetic theory of gases.

For that reason, answer is scheme (a).

Best regards.

Calculate the molar mass of NH4NO3. Molar mass of NH4NO3 = g/mol.
bija089 [108]

The molar mass of NH4NO3 in g/mol is 80g/mol.

HOW TO CALCULATE MOLAR MASS:

The molar mass of a compound can be calculated by summing the atomic masses of its constituent elements.

In ammonium nitrate (NH4NO3), there are nitrogen, hydrogen, and oxygen elements.

  • Atomic mass of nitrogen = 14
  • Atomic mass of oxygen = 16
  • Atomic mass of hydrogen = 1

Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)

Molar mass of NH4NO3 = 80g/mol

  • Therefore, the molar mass of NH4NO3 in g/mol is 80g/mol.
