Answer:

1. NO2

2.49.4%

Step-by-step explanation:

1. Find the moles of each and divide by the smallest

N: 30/14=2.14/2.14=1

O: 62/16=3.875/2.14=1.81 (round to nearest whole number)

NO2

2. Find the total mass and divide by each

Total: 291.7167

There are 9 oxygens so multiply mass by 9

16*9=144

144/291.7167=0.493629607
