To calculate the enthalpy change for the dissolution of 10 g of NaOH in 100 mL of water, we need to determine the number of moles of NaOH and then use the molar heat of dissolution to find the enthalpy change.First, let's find the number of moles of NaOH:The molar mass of NaOH = 22.99 g/mol Na + 15.999 g/mol O + 1.007 g/mol H = 39.996 g/molNow, we can find the number of moles:moles of NaOH = mass / molar massmoles of NaOH = 10 g / 39.996 g/mol = 0.2501 molNow, we can use the molar heat of dissolution to find the enthalpy change:H = moles molar heat of dissolutionH = 0.2501 mol -44.51 kJ/mol = -11.13 kJThe enthalpy change for the dissolution of 10 g of NaOH in 100 mL of water at 25C is -11.13 kJ.
