Sir.. I have doubt.... Last me Jo aap percentage of Benzene and carbon tetrachloride nikaale hai....lekin Jo formula to apne pahle bataaye hai.... No. Of atom*atomic mass*100/molecular mass
Thank you sir for making this concept easy
Sir one doubt... in 14:54 u have taken direct mass of benzene.. but in the formula u gave it was number of atom x atomic mass.. so aren't we doing the same thing in solutions case

Mass ℅ of an atom element Hydrogen = 6.6℅ of H. Mass ℅ of an atom element Oxygen = 53.3℅ of O.

For H the mass % will be 6.6666666... % so round it off to 6.7% while for O it is 53.3333333... so round it off to 53.3%.

We're so happy you're enjoying our videos and finding them helpful! The basics of chemistry are essential to understanding the world around us. Here are a few key formulas to get you started: -The Law of Conservation of Mass: Matter can neither be created nor destroyed, only changed in form. -The Law of Definite Proportions: A given compound always contains the same elements in the same proportions by mass. -The Law of Multiple Proportions: When two elements form more than one compound, the ratios of the masses of the second element that combine with a given mass of the first element are in the ratio of small whole numbers.
H.W Highest number of atom is present in (12g He) Please check my answer sir
