    Moles of methanol present in 2.5 L of 0.25 M solution

     

     

     

    Moles of CH3OH = 2.5 * 0.25 = 0.625

     

    Mass of CH3OH = 0.625 * 32 = 20 g

     

    (∵ Molecular mass of CH3OH = 12 + 1 * 3 + 16 + 1 = 32)

     

    0.793 *  g of CH3OH is present in 1000 mL

     

    20 g of CH3OH is present in

     

    =  mL
