Express your answer to three significant figures and include the appropriate units. Submit My Answers Give UR Part C How many grams of oxygen are needed to react with 165 g of hydrazine? Express your answer to three significant figures and include the appropriate units. Ask me anything

Explanation / Answer

Hydrazine, N2H4, reacts with oxygen to form nitrogen gas and water.
N2H4 (aq)+ O2 (g) ----> N2 (g) + 2H2O(l)

Part B:

GMM of hydrazine= 2×14+4=32g

32g N2H4 needs 32 g O2

165g N2H4 will required=32×165/32=165gO2

No. Of moles of O2= 165/32=5.15 moles.

Part C: 32g O2 required for 32 g N2H4.

Therefore , 165g O2 will require for 165g N2H4
