Answer:

0.264 g of [tex]CO_2[/tex] can be formed from 288 mg of [tex]O_2[/tex]

Explanation:

The balanced chemical equation is

[tex]2 C_3 H_7 OH+9 O_2> 6 CO_2+8 H_2 O[/tex]

The conversions are  

Mass in mg [tex]O_2[/tex] is converted to mass in g [tex]O_2[/tex]  

Mass in g [tex]O_2[/tex] is converted to moles [tex]O_2[/tex] by dividing with molar mass  

Moles [tex]O_2[/tex] is converted to moles [tex]CO_2[/tex]  by using the mole ratio of [tex]O_2:CO_2[/tex] is 9 : 6

Moles [tex]CO_2[/tex]  is converted to mass [tex]CO_2[/tex] by multiplying with molar mass [tex]CO_2[/tex]

mass in mg [tex]O_2[/tex]  > mass in g [tex]O_2[/tex] >moles [tex]O_2[/tex] > moles [tex]CO_2[/tex] > mass [tex]CO_2[/tex]

[tex]288mg O_2 \times \frac{(1g O_2)}{(1000mg O_2 )} \times \frac {(1molO_2)}{(32gO_2 )}\times\frac {(6mol CO_2)}{(9mol O_2 )} \times \frac {(44.0 gCO_2)}{(1mol CO_2 )}[/tex]
