How many moles of Al2(so4)3 can be produced from 7.25E24
1 answer:
12.04moles
Explanation:
Given parameters:
Number of molecules = 7.25 x 10²⁴molecules
unknown:
Number of moles = ?
Solution:
The moles of a substance is the amount of substance that contains avogadro's number of particles:
1 mole of a substance = 6.02 x 10²³
x moles of the compound will contain: }{6.02 x 10
}[/tex] = 12.04moles
This gives 12.04moles

Answer:
B) 16 g
Explanation:
- 2H₂ + O₂ → 2H₂O
First we <u>convert 4 moles of O₂ into moles of H₂</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 4 mol O₂ *
= 8 mol H₂
Finally we <u>convert 8 moles of H₂ into grams</u>, using <em>its molar mass</em>:
- 8 mol H₂ * 2 g/mol = 16 g
Thus, the correct answer is option B).
