Turn 2.41 kg into grams :
2.41 * 1000 => 2,410 g
1 cm³ = 1 mL , so:
5.00 cm³ = 5.00 mL
Therefore:
D = mass / volume
D = 2,410 / 5.00
D = 482 g/mL

the volume of a 5cm cube is 0.5dm*0.5dm*0.5dm = 0.125dm^3
1dm^3 = 1l
So 0.125dm^3 = 125mL
This gives us 2410/125 = 19.28
So the density of gold is 19.28g/mL
Final check: Gold is indeed 19.3g/mL
