The molar mass of the gas is 0.04192 M.
Molar mass is the actual weight of any element or chemical compound.
The mass of the sample is 0.500 g
The pressure is 0.230
The temperature is 25.0 C
The volume is 0.750 L
Step1 – calculate the moles
[tex]PV = nrt\\\\0.230 \times 0.750 = n \times 0.0823 \times25.0\\n = \dfrac{0.0823 \times25.0}{0.230 \times 0.750} = 11.927\;mol[/tex]
Step2 – calculate the molar mass
[tex]\rm Molar\;mass = \dfrac{mass}{number\;of\;moles} \\\\\rm Molar\;mass = \dfrac{0.500}{11.927} =0.04192[/tex]
Thus, the molar mass of the gas is 0.04192 M.
