The molar mass of the compound with 20 l volume of gas with mass of 10.0 g. is 160.51 M.
Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound.
Calculating the moles
Convert Kelvin into Celsius
[tex]\rm PV = nRT\\1 atm. \times 20.0 \times = n \times 8.314 \times 0.15 \circ C\\n = 0.0623[/tex]
Calculating the molar mass
[tex]\rm Molar\;mass = \dfrac{mass}{number\;of\;moles} \\\\Molar\;mass = \dfrac{10.0 }{0.0623} = 160.51 M[/tex]
Thus, the molar mass of the compound is 160.51 M.
