Question

The formula p=m/V, where ρ = density, m = mass, and V = volume, is used to calculate density. Solve this formula for m.

Answer 1

`m=\rho*V`

Explanation:

Note that the formula for density depends on two variables

The mass m

The volume V

`\rho=(m)/(V)`

If we have the density
`\rho` and the volume V and we want to find the mass m then we solve the equation for the variable m

`\rho=(m)/(V)`

Multiply both sides of the equality by the volume V

`(m)/(V)*V=\rho*V`

`m=\rho*V`

The formula is:

`m=\rho*V`

Answer 2

m=p*V

Explanation:

we have

p=m/V

Solve for m

That means-----> isolate the variable m

Multiply both sides by V

p*V=(m/V)*V

Simplify

p*V=m

rewrite

m=p*V
