Molar mass neon = <span>20.1797 g/mol
20.1797 g ---------- 6.02x10</span>²³ atoms
? g ------------ 3.0 x 10²³ atoms
mass = 3.0 x 10²³ * <span>20.1797 / 6.02 x 10</span>²³
mass = 6.054x10²⁴ / 6.02 x 10²³
mass = 10.05 g
hope this helps!
Answer:
Explanation:
Imagine a chemistry set in front of you
False you should only tell your teacher

Hope this helps a little :)
2 Cu + O2 = 2 CuO
2 moles Cu ----------- 1 mole O2
moles Cu -------------- 7.25 moles O2
moles Cu =7.25 * 2 / 1
moles Cu = 14.5 / 1 => 14.5 moles
Answer A
Answer:
D. all of the above.
Explanation:
The kinetic-molecular theory of gases suggests that; the particles of a gas move independently of each other, the particles in a gas move rapidly, the particles in a gas are far apart.
