Atomic number = The number of proton in an atom or ion so the right answer is 5!
<span> 4 Al(s)+3 O</span>₂<span>(g) ------------> 2 Al</span>₂<span>O</span>₃<span>(s)
3 moles O</span>₂ -------------> 2 moles Al₂O₃
? moles O₂ --------------> 1.00 mole Al₂O3
O₂ = 1.00 * 3 / 2
O₂ = 3 / 2
= 1.5 moles of O₂
Molar mass O₂ = 32.0 g
1.5 * 32.0 = 48 g of O₂
hope this helps!
Answer:
Explanation:
molecular mass of nylon ( C₁₂H₂₂N₂O₂ ) = 226 gm
Molecular mass of adipic acid = 146 gm
Molecular mass of hexamethylenediamine = 116 gm
no of moles of nylon = 36000 / 226
= 159.29
one mole of nylon requires one mole of hexamethylenediamine and one
mole of adipic acid .
159.29 mole of nylon requires 159.29 mole of hexamethylenediamine and 159.29 mole of adipic acid
159.29 mole of hexamethylenediamine
= 159.29 x 116 gm
= 18.48 kg of hexamethylenediamine
159.29 mole of adipic acid = 159.29 x 146 gm
= 23.26 kg .
18.48 kg of hexamethylenediamine and 23.26 kg of adipic acid will be required.
