Question

b. The mass of 15 cm of aluminium is 180 g. Find:
i.) the density of aluminium in kg/m”,
ii.) relative density of aluminium.​

Answer 1

$\huge\rm\underline\pink{Solution:-}$

Mass (m) = 180g = 0.18kg

Volume (v) = 15cm³ = 0.15 m³

$\large\rm\bold{\boxed{Density\:=\:\frac{Mass}{Volume}}}$

i] Density = 0.18/0.15 = 1.2kg/m³

Relative density of aluminium with respect to which should we calculate ?

Answer 2

Answer:

\huge\rm\underline\pink{Solution:-}

Solution:−

Mass (m) = 180g = 0.18kg

Volume (v) = 15cm³ = 0.15 m³

\large\rm\bold{\boxed{Density\:=\:\frac{Mass}{Volume}}}

Density=

Volume

Mass

i] Density = 0.18/0.15 = 1.2kg/m³

Relative density of aluminium with respect to which should we calculate ?
