Answer:
Moment=Force x Pivot
Explanation:
A moment is the turning effect of a force. Moments act about a point in a clockwise or anticlockwise direction.
Law of moments:

Moment=Force x Pivot
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g
