An object that weighs 150 pounds on earth weighs only 56.55 pounds on mars. the same object weighs only 24.9 pounds on the moon. what percent of an objects earths weight is its weight on mars and the moon?

Step-by-step explanation:

An object that weighs 150 pounds on earth weighs only 56.55 pounds on Mars. The same object weighs only 24.9 pounds on the moon.

To determine the percentage of an object's earth weight that would be its weight on mars, it will be (its weight on Mars / the object's earth weight) × 100%. It becomes

(56.55/150) × 100 = 37.7%

To determine the percentage of an object's earth weight that would be its weight on moon, it will be (its weight on Moon / the object's earth weight) × 100%. It becomes

(24.9/150) × 100 = 16.6%

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

207/8 is the right
