26.5 g of Fe₂(SO₄)₃

Explanation:

We have the following chemical reaction:

2 FePO₄ + 3 Na₂SO₄ → Fe₂(SO₄)₃ + 2 Na₃PO₄

number of moles = mass / molecular wight

number of moles of FePO₄ = 20 / 151 = 0.1325 moles

Taking in account the chemical reaction we devise the following reasoning:

if 2 moles of FePO₄ produces 1 mole of Fe₂(SO₄)₃

then 0.1325 moles of FePO₄ produces X moles of Fe₂(SO₄)₃

X = (0.1325 × 1) / 2 = 0.06625 moles of Fe₂(SO₄)₃

mass = number of moles × molecular wight

mass of Fe₂(SO₄)₃ = 0.06625 × 400 = 26.5 g

Answer:

6.1×10^4Pa or 61KPa

Explanation:

The Clausius-Clapeyron equation is used to estimate the vapour pressure at different temperature, once the enthalpy of vaporization and the vapor pressure at another temperature is given in the question. The detailed solution is shown in the image attached. The temperatures were converted to kelvin and the energy value was converted from kilojoule to joule since the value of the gas constant was given in unit of joule per mole per kelvin. The fact that lnx=2.303logx was also applied in the solution.
