Question

In the problem below use one of the formulas D=M/V, M=VxD, V=M/D. Don’t forget units and sig figs for your answer mass= 12.3g volume= ? Density = 8.90g/cm3

Answer 1

To find the volume using the given mass of 12.3g and the density of 8.90g/cm³, use the formula V = M / D, which yields a volume of 1.38 cm³ after considering significant figures.

Step-by-step explanation:

The student's question pertains to the calculation of volume given the mass and density of an object using the formula Volume (V) = Mass (M) / Density (D).

Since we have the mass as 12.3g and the density as 8.90g/cm³, we can plug these values into the formula to find the volume.

V = M / D = 12.3g / 8.90g/cm³ = 1.38202247191cm³

However, considering significant figures, since the mass has three significant figures and the density has three significant figures, the volume should also be reported with three significant figures.

Thus, the volume is 1.38 cm³.
