How many moles are in 34.0 g of dinitrogen oxide?

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
