The mass defect in a particular reaction is 0 . 4 g . The amount of energy liberated is n × 10 7 kW h , where n = _____. (speed of light = 3 × 10 8 m s - 1 )

Question

Aicharya · Accepted Answer

Energy liberated is given by, E = ∆ m c 2 = 0 . 4 × 10 - 3 × 3 × 10 8 2 = 3600 × 10 7 kW s = 3600 × 10 7 3600 kW h = 1 × 10 7 kW h
