1.) d = m/v.
if a substance is 10g and 20ml what is the density?
2.) d = m/v.
if a substance is 5g and 2g/ml what is the volume?
3.) d = m/v.
if a substance is 25g/ml and 100ml what is the mass?

The answer to your question is:

Explanation:

1) Data  

mass = 10 g

vol = 20 ml

     density  = 10/ 20

                 = 0.5 g/ml

2)

Data

mass = 5 g

density = 2 g/ml

        volume = mass / density

                      = 5 g / 2

                     = 2.5 g / ml

3)

Data

density = 25 g/ml

volume = 100 ml

         mass = 25 x 100

                  = 2500 g

if you're asking what comes out, it's steam.
