Mass of Neon : = 24.21564 g
Given
1.2 moles of Neon
Required
mass of Neon
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
so mass of Neon(MM=20,1797 g/mol) :
= mol x MM
= 1.2 x 20,1797
= 24.21564 g
Answer: 1.6.905.x2.00=amu
Explanation:
if you multiply the atomic mass x 2.00 it will give you 1.6.905x2.00Amu your welcome
