Answer :
To find the number of moles in a given mass of a substance, you can use the formula:
[tex]\[ \text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}} \][/tex]
For the compound [tex]\( \text{Al}_2\text{N}_3 \)[/tex], the approximate molar mass is 141.96 g/mol. If you have a mass of 6.00 grams of this compound, you can calculate the number of moles as follows:
1. Identify the given values:
- Mass of [tex]\( \text{Al}_2\text{N}_3 \)[/tex] = 6.00 grams
- Molar mass of [tex]\( \text{Al}_2\text{N}_3 \)[/tex] = 141.96 g/mol
2. Use the formula to calculate the moles:
[tex]\[ \text{Moles} = \frac{6.00 \, \text{g}}{141.96 \, \text{g/mol}} \][/tex]
3. Perform the calculation:
[tex]\[ \text{Moles} \approx 0.0423 \][/tex]
Therefore, the number of moles of [tex]\( \text{Al}_2\text{N}_3 \)[/tex] in 6.00 grams is approximately 0.0423 moles.
[tex]\[ \text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}} \][/tex]
