what mass of oxygen forms from 71.89 g co2? use the periodic table to find molar masses.71.89 g co2 = g o2

We use the ratio of the atoms C and O from the chemical formula. We calculate as follows:

71.89 g CO2 ( 1 mol CO2 / 44.01 g CO2 ) (1 mol O2 / 1 mol CO2) (32 g O2 / 1 mol ) = 52.27 g O2

Therefore, 

71.89 g CO2 =  52.27 g O2

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
