Explanation:
The mass of this iron cube depends on its side length. Assume that the side length of this cube is x. The volume of a cube is then given by:
We know that density is described as a ratio between mass and volume, meaning:
Rearranging this equation for mass, we obtain:
Substituting the value of volume and density, we get:
Based on the value of x, the mass in grams can be obtained using this equation.

2.28bar
Explanation: Boyle's law P1V1=P2V2 manipulate formula in favor of V2 the new formula should beP1V1/V2
0.895*318/125=2.2768 but to same sigfig it is 2.28
