The weight will be 1/6 time less on the moon than earth.
The varies the size of the object the effects the of gravitational pull will vary. As the moon is smaller than the size of the earth, then it has less gravitational pull. The value of gravity is [tex]9.8 ms^{-2}[/tex]on the earth but in the moon, it will reduce 1/6 times and will be [tex]1.62ms^{-2}[/tex]. The weight change by change the planet but mass remain same. In the given question the weight is 150g. So,
[tex]W = m * g[/tex]
at earth[tex]g = 9.8ms^{-2}[/tex]
by rearranging
[tex]m= W/g[/tex]
[tex]m = 150/9.8[/tex]
[tex]m = 15.3 g[/tex]
On moon [tex]g = 1.62 ms{^-2}[/tex]
[tex]m = 150/1.62[/tex]
[tex]m = 92.6 g[/tex]
The change in mass was because of gravitational pull
