    330 kg for high density liquid

    255 kg for low density liquid

    Explanation:

    Density is defined as mass per unit volume hence expressed as p=m/v where p is density, m is mass and v is volume. Making m the subject of the formula then m=pv

    The volume of the given container is given by lwh where l is length, w is width and h is height. Substituting 3m, 0.4 m and 0.5 m for l, w and h then volume is 3*0.4*0.5=0.6 cubic metres

    Since the liquids are mixed equally, volume for each is 0.6/2=0.3 cubic metres

    Mass of first liquid will be 1100*0.3=330 kgs

    Mass for other liquid whose density is 850 kg/m3 will be 0.3*850 = 255 Kgs
