Alright, lets get started.
If you have a density of 3g/ml and a volume of 10 ml
means density = 3 g / ml
Volume = 10 ml
Formula for density, mass, volume will be
[tex]density = \frac{mass}{volume}[/tex]
Plugging the value
[tex]3 = \frac{mass}{10}[/tex]
Multiplying 10 in both sides
[tex]10*3 = \frac{mass}{10} *10[/tex]
mass = 30 gm
Hence the answer is 30 gm. : Answer
Hope it will help :)
