Final answer:
The astronaut's mass on the Moon is calculated by dividing her weight by the strength of gravity, resulting in a mass of 65 kilograms.
Step-by-step explanation:
To determine the mass of the astronaut on the moon, we can use the formula for weight:
Weight = Mass × Gravity
Given that the astronaut weighs 104 newtons on the moon and the strength of gravity there is 1.6 newtons per kilogram, we can rearrange the formula to solve for mass:
Mass = Weight / Gravity
Mass = 104 newtons / 1.6 newtons per kilogram
Mass = 65 kilograms
The astronaut's mass is 65 kilograms on the Moon.
