What is the molar mass of a gas that has a mass of 0.261 g in a 0.134 l vessel at 397 k, 0.992 atm? view available hint(s) what is the molar mass of a gas that has a mass of 0.261 g in a 0.134 l vessel at 397 k, 0.992 atm? 1.15 g/mol 9.49 × 103g/mol 64.0 g/mol 171 g/mol?

-

64.0 g/mol

Explanation: -

Volume V = 0.134 L

Pressure P = 0.992 atm

Temperature T = 397 K

Using the combined gas equation

PV = nRT

Number of moles n =

=

= 0.0041

Mass = 0.261 g

Molar mass = Mass / Number of moles

=

= 64.0 g / mol

the answer is 0.8m.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
