How many newtons of force would 200 grams apply? What would be the mass of an object that weights 7 N on earth? If an object weights 450 N. How much does it weight in pounds?

The mass of an object that weights 7 N on earth would be 0.7142857... Weight = Mass x acceleration of gravity ( = 9.8) 7/ 9.8 = 0.7142857...If an object weights 450 N, then it weights 45.91 pounds.Weight = mass x acceleration of gravity (= 9.8) 450/ 9.8 = 45.918367...
