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

2.43 moles of water are required.

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

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
