Answer:
0.773 mole
Explanation:
From the question given above, the following were obtained:
Mass of dinitrogen oxide (N₂O) = 34 g
Mole of N₂O =.?
Next, we shall determine the molar mass of N₂O. This can be obtained as follow:
Molar mass of N₂O = (14 × 2) + 16
= 28 + 16 = 44 g/mol
Finally, we shall determine the number of mole in 34.0 g of dinitrogen oxide (N₂O) as follow:
Mass of dinitrogen oxide (N₂O) = 34 g
Molar mass of N₂O = 44 g/mol
Mole of N₂O =.?
Mole = mass /Molar mass
Mole of N₂O = 34/44
Mole of N₂O = 0.773 mole
Therefore, 0.773 mole is present in 34 g of dinitrogen oxide
