If relative density is 11.3, the density of the substance in SI units ...
Density is defined as the mass of a substance per unit volume. It is a measure of how much mass is packed into a given volume. In the SI (International System of Units) system, the unit of density is kilograms per cubic meter (kg/m^3).
Relative density, also known as specific gravity, is the ratio of the density of a substance to the density of a reference substance. It is a dimensionless quantity and does not have any unit. The reference substance is usually water at a specified temperature.
Given that the relative density is 11.3, we need to determine the density of the substance in SI units.
To do this, we can use the relationship between relative density and density:
Relative density = Density of substance / Density of reference substance
In this case, the reference substance is water. The density of water at 4°C is approximately 1000 kg/m^3.
So, we can rearrange the equation to solve for the density of the substance:
Density of substance = Relative density x Density of reference substance
Density of substance = 11.3 x 1000 kg/m^3
Therefore, the density of the substance in SI units is 11.3 x 1000 kg/m^3, which is option C.
