Question

How many moles of H20 are required to react completely with 7.30 moles of NO2?

3NO2(g) + H20(1)
NO(g) + 2HNO3(aq)
1.86 mol
2.19 mol
2.43 mol
6.12 mol
7.30 mol

Answer 1

2.43 moles of water are required.

Step-by-step explanation:

Given data:

Moles of H₂O required = ?

Moles of NO₂ present = 7.30 mol

Chemical equation:

3NO₂+ H₂O → NO + 2HNO₃

Now we will compare the moles of NO₂ and H₂O.

NO₂ : H₂O

3 : 1

7.30 : 1/3×7.30 = 2.43 mol
