Explanation:
elctronic configuration of manganese
Mn=1s²2s²2p⁶3s²3p⁶4s²3d⁵
ground state
Mn=Ar3d⁵4s²
note that Ar is argon
Answer: 50.9g of Fructose
Explanation:
No of moles = Mass (g) / Molar Mass (g/mol)
Moles = 0.283
Molar Mass of Fructose (C6H12O6) = 12 x 6 + 1 x 12 + 16 x 6 = 180g/mol
Mass = ?
Make 'Mass' the subject of formular, we will have;
Mass = Molar Mass x No of moles
= 180g/mol x 0.283
= 50.9g of Fructose
Answer:
C₆H₆
Step-by-step explanation:
<em>Data:
</em>
EF = CH
MF mass = 78.11 u
<em>Calculations:
</em>
EF Mass = (12.01 + 1.008) u
EF Mass = 13.018 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
n = MF Mass/EF Mass
n = 78.11 u/13.02 u
n = 6.000 ≈ 6
MF = (CH)₆
MF = C₆H₆
