Answer:
1. 1g/ml
Explanation:
1. Density is mass divided by volume (g/mL).
10g/10mL = 1 g/mL
2. When you already know the density and the volume, you can use the density as a unit converter.
[tex]5mL*\frac{20g}{mL} = 100g[/tex]
3. It's the same with density and mass.
[tex]20g*\frac{1mL}{5g} = 4mL[/tex]
