<span><span>N2</span><span>O5</span></span>
Explanation!
When given %, assume you have 100 g of the substance. Find moles, divide by lowest count. In this case you'll end up with
<span><span>25.92 g N<span>14.01 g N/mol N</span></span>=1.850 mol N</span>
<span><span>74.07 g O<span>16.00 g O/mol O</span></span>=4.629 mol O</span>
The ratio between these is <span>2.502 mol O/mol N</span>, which corresponds closely with <span><span>N2</span><span>O5</span></span>.
C3H8 -----> 3 CO2 (from equation)
1mol C3H8 ------ 3 mol CO2
2.0 mol C3H8 ---- x mol CO2
x=(2.0 mol C3H8* 3 mol CO2)/1mol C3H8 =6 mol CO2
