Answer: 581 gmol
0.581 kmol

Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:

1. The conversion for mol to gmol
1 mol = 1 gmol
581 mol= 
2. The conversion for mol to kmol
1 mol = 0.001 kmol
581 mol= 
3. The conversion for mol to lbmol
1 mol = 
581 mol= 
Answer:
B 1.87×10^-²
Explanation:
20.1797 g Neon = 1 mol
0.378 g Neon = y
(Cross multiply)
20.1797y= 0.378 x 1
(Make y the subject of the formula)
y = 0.878/ 20.1787
y = 0.0187317
y = 0.0187 approx
y = 1.87 x 10^-²
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number.
