Answer:
218.98 grams
Explanation:
Given that,
No. of moles, n = 2.3
The molar mass of magnesium chloride is 95.211 g/mol.
We need to find the mass of 2.3 moles of magnesium chloride.
We know that,
No. of moles = given mass/molar mass
Let m be the given mass. So,
[tex]m=n\times M\\\\=2.3\times 95.211 \\\\=218.98\ g[/tex]
So, the required mass is equal to 218.98 grams.
Which statement describes particles of an ideal gas, based on the kinetic molecular theory?
Answer:
There are 5 steps/rules of the ideal gases based on kinetic theory.
Explanation:
1. Particles in a gas are constant moving in random motion.
2. combined volume of the particles is negligible.
3. particles exert no forces on one another
4. any collisions between the particles are completely elastic
5. the average kinetic energy of particles is proportional to temperature in kelvins.
