The exhaust of a vehicle includes 14.50 volume percent of co2 and 375 ppm of no. the molecular weight of co2 is 44 g/gmol. for no, by convention we always use a molecular weight of 46 g/gmol to represent and equivalent amount of no2. gasoline has density of 2791.0 g/gallon and contains 86.5 weight percent of carbon assume that all carbon in the fuel is emitted as co2. what is the emission rate of no in units of grams of equivalent no2 per gallon of fuel consumed? [hint: one step is to figure out the gmol of c in the fuel based on the mass of carbon in each gallon of fuel.]

the ratio of the conjugate base to the acid required to attain the desired ph.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
