Answer:

12.5 grams.

Step-by-step explanation:

NO has an equal amount of N and O (one of each). In order to produce 50 grams of NO, you'd need 25 grams of each. However, since O2 has two molecules of oxygen, you'd cut that in half.

Hope this helps!

Answer:

26.67g of O2

Step-by-step explanation:

Let ur generate a balanced equation for the reaction. This is shown below:

N2 + O2 —> 2NO

Molar Mass of O2 = 16x2 = 32g/mol

Molar Mass of NO = 14 + 16 = 30g/mol

Mass of NO from the balanced equation = 2 x 30 = 60g

From the equation,

32g of O2 is required to produced 60g of NO.

Therefore, Xg of O2 will be required to produce 50g of NO i.e

Xg of O2 = (32x50) /60 = 26.67g

Therefore, 26.67g of O2 are needed.
