Hi I was wondering if someone cn help me with a titration calculation
The queztion asks to calculate the molecular mass of hydrated washing soda deduced from experimental data. The experiment goes like this we have been provided N/10 Hcl solution and a solution prepared by dissolving 7.1g of Na2co3.xh20 per litre of the solution. The titre value I got was 25.4.
The normality of this came to 0.1016N
