Balance the following chemical equation, then answer the following question. c8h18(g) + o2(g) → co2(g) + h2o(g) how many grams of oxygen are required to react with 10.0 grams of octane (c8h18) in the combustion of octane in gasoline?

Molar mass

C8H18 => 114.23 g/mol
O2 => 31.99 g/mol

2 C8H18 + 25 O2 ---> 16 CO2 + 18 H2O

2 x 114.23 g 25 x 31.99 g
10.0 g ( mass of O2)

mass of O2 = 10.0 x 25 x 31.99 / 2 x 114.23

mass of O2 = 7997.5 / 228.46

= 35.00 g of O2

hope this helps!

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.
