(I'm not sure what the unit "m1" is. Do you mean ml for milliliters? I am going to use ml in this problem.)
Volume= 130ml
Mass= 585g
The formula for density is
Density=Mass/Volume
All you have to do is pop the information in the formula Density= 585g/130ml
585/130= 4.5
you can't divide g/ml, so just leave it the way it is
Therefore the answer is
Density= 4.5 g/ml
Hope this helps!
