Explanation:
Given the following data:
According to the ideal gas law, we know that the product between pressure and volume of a gas is equal to the product between moles, the ideal gas law constant and the absolute temperature:
Since the temperature and the ideal gas constant are constants, as well as the fixed container volume of 5 L, we may rearrange the equation as:
This means for two conditions, we'd obtain:
Given:
Solve for the final pressure:
Now, according to the Dalton's law of partial pressures, the partial pressure is equal to the total pressure multiplied by the mole fraction of a component:
Knowing that:
And:
The equation becomes:
Substituting the variables:
Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force
N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
