Question

the mass of the stone is 150g and its volume is 75g cm³. calculate the density of the stone​

Answer 1

➠ Given:

Mass = 150 g

Volume = 75 cm³

➠ Solution :-

By applying,

density = mass ÷ volume

⟹ Density = 150g / 75 cm³

∴ Density = 2 g/cm³

Answer 2

Answer:

2000 kg/$m^{3}$

Explanation:

As you most likely know, density = mass/volume

HOWEVER, before doing the division, we must convert the values into suitable units in order to get the answer in the standard unit that is kg/$m^{3}$.

150g= 0.15 kg (1000g=1kg)

75 c$m^{3}$= 75/(100*100*100)= 0.000075 $m^{3}$ (This may seem like a very small no., but when we divide, it gets in the denominator!)

So, 0.15kg/0.000075$m^{3}$= 2000kg/$m^{3}$
