The density of a liquid is 750 kg/m³. what will be its relative density? (Density of water at 4°C is 1000 kg/m³.)
R. Density = 750/1000 = 0.75.
To find the relative density, we need to compare the density of the given liquid to the density of water at a specified temperature.
Given:
Density of the liquid = 750 kg/m³
Density of water at 4°C = 1000 kg/m³
We can calculate the relative density using the formula:
Relative Density = Density of the liquid / Density of water at the specified temperature
Substituting the given values into the formula, we have:
Relative Density = 750 kg/m³ / 1000 kg/m³
Simplifying the equation, we get:
Relative Density = 0.75
Therefore, the relative density of the given liquid is 0.75.
To find the relative density of a liquid, you need to compare its density to the density of water at a specific temperature.
Relative density is defined as the ratio of the density of a substance to the density of a reference substance (usually water). In this case, the reference substance is water at 4°C.
Given that the density of water at 4°C is 1000 kg/m³ and the density of the liquid in question is 750 kg/m³, we can now calculate the relative density.
Relative density = Density of the liquid / Density of water at 4°C
Relative density = 750 kg/m³ / 1000 kg/m³
Relative density = 0.75
Therefore, the relative density of the liquid is 0.75.
