A compound is composed of carbon and hydrogen, in which the mass fraction of carbon is 85.7% and the mass of 11.2 L gas is 14 g under standard conditions. Using the simplest formula The amount ratio of c to h is 1:2, How did you get this?
Using the simplest formula, the mass fraction of carbon is 85.7%, and the mass fraction of hydrogen is 1-85.7%=14.3%. The ratio of the number of C and H atoms to the amount of substance equal to C and H atoms is =(85.7%/12):(14.3%/1)==1:2, so the simplest formula is CH2. Under the standard condition, the mass of 11.2 L of this compound gas is 14 g, and the amount of substance is 11....
