| Question | Answer |
| Relative Atomic Mass (RAM) | RAM of an element = mass of one atom of the element divided by 1/12 x mass of one atom of C12. |
| Mass Percentage | Mass Percentage of a component = mass of the component ------------------------------------ x 100 mass of the solution |
| Volume Percentage | Volume Percentage of a component = Volume of the component ------------------------------------ x 100 Total volume of the Solution |
| Mole Fraction | M.F. of A (xA) = nA (no. of moles of the component) --------------------------------------------------- nA + nB + n... (total no. of moles) |
| Number of Moles | given mass nX = ---------------- . molar mass |
| Molality (m) | number of moles of the solute m = ------------------------------------------- weight of the solvent in kg unit: mole/kg |
| Molarity (M) | number of moles of the solute M = ------------------------------------ volume of the solution in liters unit: mole/l |
| Normality (N) | no of gram-equivalents of solute N = ---------------------------------------- volume of the solution in liters unit: gram-equivalent/l |
| Equivalent Mass | atomic mass ------------------ valency |
| No of gram-equivalents | given mass ------------------------ equivalent mass |
