Question

1liter gram water me hydrogen and oxygen che mass kitna hota hai? ye kaisa nichhit kiya?​

Answer 1

Answer:

{Given atomic mass oxygen =16, Hydrogen = 1}

molecular mass of H2O = { 1*2+16}

                                        = 18 a.m.u

percentage composition of H = { ( 2/18 )* 100 }  %            

                                                  =11.11 %

percentage composition of O = { ( 16/18 ) * 100 } %

                                                   =88.89%

1 Liter of water = 1000 ml of water

therefore mass of H in 1 l of H20 is = [ ( 11.11/100)*1000/100 ]

                                                         = 1.11 g

therefore mass of O in 1 L of H2O is = { ( 88.89/100 ) * 1000/100 ]

                                                             = 8.89
