Question

The equation d=m/v can be used to calculate the density,d, of an object with mass,m,and volume,v.which is an equivalent equation solved for v

Answer 1

V = M/D

Explanation:

D = Density

M = mass

V = Volume

Volume for Density:

D = M/V

If we want to find volume we just rearrange the equation:

V = M/D

We can plug in the numbers to check whether or not this equation is true. Say we need to find density and the volumes & mass are already given (V=5 cm^3 and M=10g)

So, 10g/5cm^3 = D

2g/cm^3 = Density

Using the following numbers we can now find the Volume. Say we don't know that 5cm^3 is the volume and we are only given the Density (2g/cm^3) and Mass (10g). We plug those values into the equation V=M/D:

V = 10g/2g/cm^3

V = 5cm^3

The grams cancel out and we are only left with the cm^3 part.

Hope that explains it :)
