Answer :
Final answer:
The mass of 0.75 moles of vanadium (i) oxide (V₂O) is approximately 50.205 grams.
Explanation:
To calculate the mass of 0.75 moles of vanadium (i) oxide (V₂O), we need to find the molar mass of the compound and then multiply it by the number of moles. The molar mass of V₂O is calculated as follows:
Molar mass of V: 50.94 g/mol
Molar mass of O: 16.00 g/mol
Add the molar masses of V and O: 50.94 g/mol + 16.00 g/mol = 66.94 g/mol
Now, multiply the molar mass by the number of moles:
0.75 moles * 66.94 g/mol = 50.205 g
So, the mass of 0.75 moles of vanadium (i) oxide is approximately 50.205 grams.
