    oh yes, 2C8H18 + 25 O2 yields 16 CO2 + 18H2O

    Don't worry :) \[2C_8H_{18} + 25O_2 \rightarrow 16CO_2 +18H_2O\] no. of mole of CO2 produced required = 100/(12.0+16.0x2) = a No. of mole of C8H18 required = No. of mole of CO2 x (2/16) = a/8 = b Mass of C8H18 required = no. of mole of C8H18 required x (12.0x8 + 1.0x18) = b x (12.0x8 + 1.0x18) = answer you need. Is it clear?

    That seems generally what I did
