In the following reaction, how many grams of oxygen will react with 10.47 grams of benzene (c6h6)? 2c6h6 + 15o2 12co2 + 6h2o the molar mass of benzene is 78.1074 grams and that of o2 is 32 grams.

The balanced chemical reaction will be:

We are given the amount of benzene to react with oxygen gas. This will be our starting point.

10.47 g C6H6 ( 1 mol C6H6 / 78.1074 grams C6H6) (15 mol O2/2 mol C6H6 ) ( 32 g O2 / 1 mol O2) =  32.1711g O2

32.171087  grams of oxygen will react with 10.47 grams of benzene.

Explanation:

Moles of benzene =

According to reaction ,2 moles of benzene reacts with 15 moles of oxygen

Then 0.1340462 moles of benzene will react with:

of oxygen

Mass of 1.0053464 moles of oxygen ;

32.171087  grams of oxygen will react with 10.47 grams of benzene.
