Explanation:
Weight of an object is shows the force of gravity acting on it. It is calculated mass times acceleration due to gravity.
lb is the unit of avoirdupois weight. It means that 12 lb shows weight.
gram, kg is the unit of mass. It means 0.34 g and 120 kg shows mass of an object.
m and cm are the units of length. It means 0.34 m and 411 cm shows the length of the object.
N is the unit of weight.
Hence, 12.0 lb and 1600 kN are acceptable representations of weight.
