2C6H14+19O2 (Arrow)12CO2+14H2O

99.01 g of CO2=..........mol of O2?

188.73g of O2=..............g of C6H14?

To find the number of moles of O2 in 99.01 g of CO2, you can use the molar ratio from the balanced chemical equation.

In the given equation, the molar ratio between CO2 and O2 is 12:19. This means that for every 12 moles of CO2, there are 19 moles of O2.

Step 1: Convert the mass of CO2 to moles.
To do this, use the molar mass of CO2, which is 44.01 g/mol.

Number of moles of CO2 = Mass of CO2 / Molar mass of CO2
Number of moles of CO2 = 99.01 g / 44.01 g/mol

Step 2: Use the molar ratio to find the moles of O2.
Since the molar ratio between CO2 and O2 is 12:19, multiply the number of moles of CO2 by the ratio.

Number of moles of O2 = Number of moles of CO2 × (19 moles of O2 / 12 moles of CO2)

Now, let's calculate the value:

Number of moles of O2 = (99.01 g / 44.01 g/mol) × (19/12)
≈ 2.82 mol of O2

Therefore, 99.01 g of CO2 is approximately equal to 2.82 moles of O2.

Moving on to the next question:

To find the amount of C6H14 (hexane) in 188.73 g of O2, we need to follow a similar process, using the molar ratio between O2 and C6H14.

But there is no direct molar ratio mentioned in the given equation. To find the molar ratio, we need to first balance the equation. It should be noted that the given equation is incomplete and cannot be balanced without additional information.

Once we have a balanced equation, we can determine the molar ratio between O2 and C6H14, which will allow us to convert grams of O2 to grams of C6H14.

Please provide the balanced equation or any additional information to proceed with the calculation.
