Answer:
102.8 kPa.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm (P = ??? atm).
V is the volume of the gas in L (V = 4000 mL = 6.23 L).
n is the no. of moles of the gas in mol (n = 0.25 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 35ºC + 273 = 308 K).
∴ P = nRT/V = (0.25 mol)(0.0821 L.atm/mol.K)(308 K)/(6.23 L) = 1.015 atm.
<em><u>multiply the pressure value by 101.325
</u></em>
∴ P = (1.0 atm)(101.325 kPa/1.0 atm) = 102.8 kPa.
<span>Hydration can occur when one mole of sodium acetate trihydrate is heated. Sodium acetate or NaC2H3O2 3H2O contains three water molecules within each unit in the crystal. The corresponding amount of hydration energy is already released when sodium acetate absorbs water and is then converted to sodium acetate trihydrate.</span>
