What is the mass of glucose in 435 ml of a 12.0% (w/v) glucose solution?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

given information:

2c6h14 + 19o2 → 12co2 + 14h2o

moles of co2 produced = 18.4

to determine:

moles of c6h14 required to produce 18.4 moles of co2

explanation:

based on the combustion reaction stoichiometry:

2 moles of c6h12 burns to produce 12 moles of co2

i.e.

6 moles of co2 are produced by burning 1 mole of c6h12

thus, 18.4 moles of co2 would require: 18.4 co2 * 1 c6h12/6 co2 = 3.07 moles of c6h12

ans: (b)
