Question

Explain density and relative density write their formulae ​

Answer 1

Answer:

This means that density of any solid,liquid, or gas can be found by dividing its mass in kilogram by its volume in cubic metres. Density of a substance is defined as its mass per unit volume. Relative density of a substance is defined as the ratio of its density to that of water at 4°c.

Explanation:

please follow me.

Answer 2

Question:

Explain density and relative density write their formulae .

Answer:

Density:-

Density of a substance is defined as its mass per unit volume.

Formula:-

$\large{ \bf\red{Density = \frac{mass \: of \: a \: substance}{volume \: of \: that \: substance} }}$

SI unit:-

• SI unit of density is per cubic meter

$\bf{kg {m}^{ - 3} }$

Example:-

• For example, the mass of 5 litre of water is 5 kg.

$\large \bf{1 \: liter = 10 {}^{ - 3} {m}^{3} } \\ \large \bf{5 \: liter = 5 \times 10^{ - 3} {m}^{3} } \\ \large \bf{Density \: of \: water = \frac{5kg}{5 \times 10^{ - 3} {m}^{3} } } \\ \: \: \: \: \: \: \: \: \: \: \: \large \bf{ = 1000kg {m}^{ - 3} }$

• So the density of water is 1000kgm-3.
