Answer:
The correct answer is 10.939 mol ≅ 10.94 mol
Explanation:
According to Avogadro's gases law, the number of moles of an ideal gas (n) at constant pressure and temperature, is directly proportional to the volume (V).
For the initial gas (1), we have:
n₁= 1.59 mol
V₁= 641 mL= 0.641 L
For the final gas (2), we have:
V₂: 4.41 L
The relation between 1 and 2 is given by:
n₁/V₁ = n₂/V₂
We calculate n₂ as follows:
n₂= (n₁/V₁) x V₂ = (1.59 mol/0.641 L) x 4.41 L = 10.939 mol ≅ 10.94 mol
Ammonium magnesium phosphate hexa-hydrate usually looses its water of crystallization in a gradual manner. At the temperature above 100 degree Celsius the compound would have lost all its water of crystallization.<span />
Sound is created by the vibrations of matter such as air. But theoretically if someone tried to make a sound in space where there is no matter, there would be nothing to vibrate so it wouldn’t make sound.
So no, sound needs matter to travel because sound itself is the vibration of matter.

Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Atoms are more stable when they have no charge, or a small charge
