Concentration of a solution can be expressed in : 1. Molarity 2. Molality Select the answer using the code given below :
Both 1 and 2
The concentration of a solution can be expressed using several measures, including molarity (moles of solute per litre of solution) and molality (moles of solute per kilogram of solvent). Both are valid and widely used, so the correct choice is 'Both 1 and 2'.
Which one of the following statements is true when non-metals are dissolved in water?
What will happen to the boiling point of water when a little common salt is added to water and then heated?
Which Statement is correct ?
The pH value of 1 × 10 -8 (M) HCl is:
Tyndall effect is not observed in:
A non-volatile solute, urea ($CO(NH_2)_2$, molar mass $60 \ g/mol$), is dissolved in $180 \ g$ of water ($H_2O$, molar mass $18 \ g/mol$). If the vapor pressure of pure water at a certain temperature is $50 \ mmHg$, what is the vapor pressure of the solution when $18 \ g$ of urea is added?
