[tex]Dane:\\m = 4 \ g\\V = 2 \ cm^{3}\\Szukane:\\d = ?[/tex]
Gęstość jest ilorazem masy i objętości:
[tex]d = \frac{m}{V}\\\\d = \frac{4 \ g}{2 \ cm^{3}}=2\frac{g}{cm^{3}}\\\\2\frac{g}{cm^{3}}= 2\cdot\frac{\frac{1}{1000} \ kg}{\frac{1}{1000000}m^{3}}} = 2\cdot1000\frac{kg}{m^{3}} = 2000\frac{kg}{m^{3}}\\\\\boxed{d = 2\frac{g}{cm^{3}} = 2000\frac{kg}{m^{3}}}[/tex]
