A1.900 g sample of c6h12 is burned in an excess of oxygen. what mass of c)2 and h20 should be obtained

The balanced chemical reaction is:

C6H12 + 9O2 = 6CO2 + 6H2O

We are given the amount of C6H12 to be used for the reaction. THis will be the starting point for the calculations.

1.900 g C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol CO2 / 1 mol C6H12) (44.01 g /mol ) = 5.96 g CO2
1.900 g C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol H2O / 1 mol C6H12) (18.02 g /mol ) =  2.44 g H2O

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

I’m not sure what your trying to say here.. can you clarify again?
