AP24 Q2 Class 12 (Solution Conc., Titration, KMT 1)

Front

What is the formula for calculating pressure in a manometer?

Back

Pressure (P) = height of liquid column (h) × density of liquid (ρ) × gravitational acceleration (g).

Front

Define molarity (M).

Back

Molarity (M) is the number of moles of solute per liter of solution.

Front

What is the molecular weight of a compound?

Back

The molecular weight is the sum of the atomic weights of all atoms in a molecule, expressed in grams per mole (g/mol).

Front

How do you calculate the concentration of a solution after a titration?

Back

Concentration (C) = (moles of solute / volume of solution in liters).

Front

What is the relationship between pressure, volume, and temperature of a gas?

Back

This relationship is described by the Ideal Gas Law: PV = nRT.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.

Front

What is the significance of significant figures in calculations?

Back

Significant figures indicate the precision of a measurement and should be maintained in calculations to avoid rounding errors.

Front

What is the density of a solution?

Back

Density (d) is defined as mass (m) divided by volume (V): d = m/V.

Front

What happens to the pressure of a gas if the number of molecules is increased while keeping temperature and volume constant?

Back

The pressure increases due to more collisions of gas molecules with the walls of the container.

Front

What is the effect of temperature on gas pressure?

Back

At constant volume, increasing temperature increases the pressure of a gas due to increased kinetic energy of molecules.
