Calculating the Mass of Sodium Formate
Basic Calculations
Calculating the mass of sodium formate in a solution involves understanding its concentration and volume. The basic formula is:
[ \text{Mass} = \text{Concentration} \times \text{Volume} ]
- Concentration: The amount of sodium formate per unit volume of solution, typically expressed in mol/L (molarity) or g/L.
- Volume: The total volume of the solution in liters (L).
Practical Example
Consider a solution with a concentration of 2 mol/L and a volume of 0.5 L. The molar mass of sodium formate (HCOONa) is approximately 68.01 g/mol. The mass of sodium formate can be calculated as follows:
[ \text{Mass} = \text{Concentration} \times \text{Volume} \times \text{Molar Mass} ]
[ \text{Mass} = 2 \text{ mol/L} \times 0.5 \text{ L} \times 68.01 \text{ g/mol} ]
[ \text{Mass} = 68.01 \text{ g} ]
