Refer to the following unbalanced equation: co2 h20 c6h14 o2> co2 + h2o what mass of oxygen (o2) is required to react completely with 10.4 g of c6h14? d. 36.7 g selected d. 36.7 g correct

The mass of oxygen gas required is 36.7 grams.

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of hexane = 10.4 g

Molar mass of hexane = 86.18 g/mol

Putting values in equation 1, we get:

The chemical equation for the combustion of hexane follows:

By stoichiometry of the reaction:

2 moles of hexane reacts with 19 moles of oxygen gas

So, 0.12 moles of hexane will react with = of oxygen gas.

Now, calculating the mass of oxygen gas by using equation 1, we get:

Molar mass of oxygen gas = 32 g/mol

Moles of oxygen gas = 1.14 moles

Putting values in equation 1, we get:

Hence, the mass of oxygen gas required is 36.7 grams.

i think so it’s will be b yes i believe its
