An astronaut in a spacesuit has a mass of 100 kilograms. what is the weight of this astronaut on the surface of the moon where the strength of gravity is approximately 1/6 that of earth?

The definition of weight allows finding the result of the astronaut  Moon's weight is 163 N

The weight of a body is the attractive force of the planet on the body

         W = m g

Where W is the weight, m the mass of the body and g the acceleration due to gravity

In this case the astronaut is on the Moon, I have indicated that the Moon's gravity is

Where is gravity on the moon, is gravity on earth

            = 1/6 9.8

           g_m = 1.63 m / s²

In the attached we have a diagram of the weights on the Earth and the moon.

They indicate that the mass of the astronaut is 100 kg, let's calculate the weight on the moon

          W = 100  1.63

           W = 163 N

In conclusion using the definition of weight we can find the result of the astronaut's  Moon weight  is 163 N
