The molecular formula of the given compound is CH₅N.
<h3>What is the ideal gas equation?</h3>
The ideal gas law has defined the product of the volume and pressure as equal to the product of the gas constant (R) and absolute temperature of the gas.
The mathematical equation of the ideal gas law is as follows:
PV = nRT
The temperature of the compound, T = 22° C = 295 K
The pressure of the compound, P = 99.5 KPa = 0.982 atm
The volume of the compound, V = 125 ml = 0.125 L
0.125 × 0.982 = (0.157 g/M) × 0.082 ×295
M = 31 g/mol
A number of moles of C = 0.157 ×0.37/12 = 0.00484
A number of moles of N = 0.157 ×0.45/14 = 0.00504
A number of moles of H = 0.157 ×0.16/1 = 0.0251
The simplest ratio of C: N: H is 1 : 1 : 5
The empirical formula of the given compound is CH₅N.
The molecular formula of the compound is CH₅N as the molecular mass is equal to 31 g/mol.
