Assume gasoline to be 87 vol% iso-octane (2,2,4 tri-methyl pentane) and 13 vol% -heptane. At room temperature, the air above a pool of gasoline will become saturated

1. Is the air-gasoline mixture within its flammable limits?
2. Could there be any location where the mixture will be within its flammable limits? Explain.
