Answer:
Ro = 1000 [kg/m³]
Explanation:
We must remember that density is defined as the relationship between mass and volume.
[tex]Ro=m/V\\[/tex]
where:
Ro = density [kg/m³]
m = mass = 3 [kg]
V = volume = 3000 [ml]
We must convert the volume of milliliters to cubic meters
[tex]3000[ml]*\frac{0.001Lt}{1ml}*\frac{1m^{3} }{1000Lt} = 0.003m^{3}[/tex]
Now replacing:
[tex]Ro=3/0.003\\Ro=1000[kg/m^{3} ][/tex]
