Answer:

Formula: Na2S2O3

we get solubility.

Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

Solution given:

mass of sodium thiosulphate [m1]=25.5g

mass of water [m2]=40g

at temperature [t]=25°C

we have

<u>solubility in g/dm^3</u> :\frac{solute in gram}{solvent in gram} *100

  • =\frac{25.5}{40}*100
  • =63.75g /litre=63.75g/dm³

<u>solubility in g/dm^3 :63.75g/dm³</u>

<u>n</u><u>o</u><u>w</u>

solubility of the solute in mol/dm^3=:63.75g/dm³/178=0.4 mol/dm³

Give an example of a state function and explain why it is a state function
inessss [21]
  • A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function. 
  • While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
  • The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
  • State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
  • They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.
