Answer 1

Explanation:

Density = mass / volume

Density = 5.4/2

Density = 2.7 Ans

Answer 2

Solution:-1

• Relative Density=1.43

We know

$\boxed{\sf Relative\:Density=\dfrac{Density\:of\:substance}{Density\:of\:water\:at\:4°C}}$

$\\ \sf\longmapsto Density\:of\:substance=Relative \:Density\times Density\:of\;water\:at\:4°C$

$\\ \sf\longmapsto Density\;of\:substance=1.43\times 1000$

$\\ \sf\longmapsto Density\:of\:subsrance=1430kg/m^3$

Solution:-2

• Mass=5.4g
• Volume=2cm^3

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{5.4}{2}$

$\\ \sf\longmapsto Density=2.7g/cm^3$
