Answer:
N3H12PO3
Explanation:
Step 1:
Data obtained from the question.
Nitrogen (N) = 31.57%
Hydrogen (H) = 9.10%
Phosphorus (P) = 23.27%
Oxygen (O) = 36.06%
Step 2:
Divide by their molar masses.
This is illustrated below:
N = 31.57/14 = 2.255
H = 9.10/ 1 = 9.1
P = 23.27/31 = 0.751
O = 36.06/16 = 2.254
Step 3:
Divide by the smallest number. This is illustrated below:
N = 2.255/0.751 = 3
H = 9.1 /0.751 = 12
P = 0.751 /0.751 = 1
O = 2.254/0.751 = 3
The empirical formula is N3H12PO3

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.
