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:
a) 2.01 g
Explanation:
- Na₂CO₃ (s) + 2AgNO₃ (aq) → Ag₂CO₃ (s) + 2NaNO₃
First we <u>convert 0.0302 mol AgNO₃ to Na₂CO₃ moles</u>, in order to <em>calculate how many Na₂CO₃ moles reacted</em>:
- 0.0302 mol AgNO₃ *
= 0.0151 mol Na₂CO₃
So the remaining Na₂CO₃ moles are:
- 0.0340 - 0.0151 = 0.0189 moles Na₂CO₃
Finally we <u>convert Na₂CO₃ moles into grams</u>, using its <em>molar mass</em>:
- 0.0189 moles Na₂CO₃ * 106 g/mol = 2.003 g Na₂CO₃
The closest answer is option a).
