    Soln
    Given: volume of NaOH =25cm³
    volume of H2SO4 =20cm³
    Motality of base =0.1mol/dm³
    Required to calculate
    Conc of H2SO4 =?
    Mass of H2SO4 =? In 250cm³=0.25dm³ of the Solution
    Equation 2NaOH+H2SO4---->Na2SO4+2H2O
    From
    MaVa/Na=MbVb/Nb
    Where by
    Ma motality of acid
    Va volume of acid
    Na no of moles of acid
    b=base
    Then
    Ma=Na×Mb×Vb÷Va×Nb
    Ma=1×0.1×25÷20×2
    Ma=0.06mol/dm³
    but
    Ma=conc÷molar mass of H2SO4
    conc=Ma×98g/mol
    Conc=0.06mol/dm³×98g/mol
    Conc=5.88g/dm³
    Also Conc =masa÷volume
    Mass=Conc ×volume
    Mass=5.88g/dm³×0.25dm³
    Mass=1470g

    Introduction to organic chemistry

    organic chemistry all deals with the study of all organic components that makes up a compound. specifically the element that makes up most of the organic compounds is carbon.
    carbon makes up the organic compounds since it neither have metallic or non metallic characters. in addition to that carbon is or has 4 free space or lone ions that at most case are occupied by elements such as chlorine, iodine ,hydrogen ,boron ,iodine etc
    plastic is one among of exanple of an organic component that is made up of hydrocarbons
