Express Strength of 0.5 Na2CO3 Solution in Gram per Litre
Na2CO3 is the chemical formula for sodium carbonate, which is a white, crystalline solid commonly known as soda ash or washing soda. It is a strong base and has various industrial applications, such as in the manufacturing of glass, chemicals, and detergents.
To express the strength of a sodium carbonate solution, we need to determine the concentration of the solution in grams per litre. The concentration represents the amount of solute (sodium carbonate) dissolved in a given volume of solvent (water).
To calculate the strength of a 0.5 Na2CO3 solution in grams per litre, we need to consider the molar mass of sodium carbonate and the given concentration.
1. Determining the Molar Mass of Sodium Carbonate (Na2CO3)
The molar mass of sodium carbonate can be calculated by adding the atomic masses of its constituent elements, which are:
- Sodium (Na): atomic mass = 22.99 g/mol
- Carbon (C): atomic mass = 12.01 g/mol
- Oxygen (O): atomic mass = 16.00 g/mol
Using these atomic masses, we can calculate the molar mass of sodium carbonate as follows:
Molar mass of Na2CO3 = (2 * atomic mass of Na) + atomic mass of C + (3 * atomic mass of O)
= (2 * 22.99 g/mol) + 12.01 g/mol + (3 * 16.00 g/mol)
= 105.99 g/mol
2. Calculating the Concentration in Grams per Litre
The given solution is a 0.5 Na2CO3 solution, which means that there is 0.5 moles of sodium carbonate dissolved in 1 litre of solution. To express this concentration in grams per litre, we need to convert moles to grams.
- Convert moles to grams:
Number of moles = Concentration in moles per litre (0.5 mol/L) * Volume in litres (1 L)
= 0.5 mol
Mass of sodium carbonate = Number of moles * Molar mass of Na2CO3
= 0.5 mol * 105.99 g/mol
= 52.995 g
Therefore, the strength of the 0.5 Na2CO3 solution is 52.995 grams per litre.
In summary, the concentration of the 0.5 Na2CO3 solution is 52.995 grams per litre. This means that for every litre of the solution, there are 52.995 grams of sodium carbonate dissolved in it.
