carbon and oxygen combine to form carbon dioxide gas.they do so in the same ratio 3:8 .what mass of oxygen would be required to react completely with 6.0g of carbon? also calculate the mass of carbon dioxide gas so formed. which law of chemical combination will govern our answer?
3g of carbon combines with 8g of O2
LET MASS Of c combining with 6g of O2 be Xg
3/8=X/6
X =3/8 *6
X =0.75*6
X=2.25
here the law of definite proportions will govern us
hope this would be a good answer for you
