mass = 20 pounds = 254193.237 g. Gravity of sun = 28.02 g m − 1 28.02 gm^{-1}

Weight = m a s s × g r a v i t y = 254193.237 ∗ 28.02 = 254193.237 mass \times gravity = 254193.237 * 28.02 = 254193.237

So, weight = 254193.237g or 560.4001 pounds ~ 560 pounds

Since the suns gravitational tug is 28 times stronger than earth, then a person on the sun is 28 times heavier than when he/she was on earth. If she weighs 20 pounds, then she would weight 560 pounds on the sun.
