The value of m is and the value of b is .

Further Explanation:

The property is a unique feature of the substance that differentiates it from the other substances. It is classified into two types:

1. Intensive properties:

These are the properties that depend on the nature of the substance. These don’t depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, molarity, concentration, pressure, and density are some of the examples of intensive properties.

2. Extensive properties:

These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, enthalpy, volume, energy, size, weight, and length are some of the examples of extensive properties.

Density is defined as the ratio between mass and volume. Both mass and volume are the physical properties that are extensive in nature and their ratio comes out to be an intensive quantity that depends only on the nature of the substance, not on the amount of the substance. The formula to calculate the density of a substance is,

Molarity is a concentration term that is defined as the number of moles of solute dissolved in one litre of the solution. It is denoted by M and its unit is mol/L.

The formula to calculate the molarity of the solution is as follows:

The given expression is,

…… (1)

Substitute the formula of given quantities in equation (1).

…… (2)

Quantities with same units are added, subtracted, multiplied or divided. So two quantities on the right-hand side of equation (2) must have the same units and equation (2) becomes,

…… (3)

Solve for units of m,

Or it can be written as,

…… (4)

Substitute 58.5 g/mol for the molar mass of NaCl in equation (4).

The unit of b is equal to that of m(density). So its unit can be calculated as follows:
