Gas has a volume of 247.3 ML and is at 100 Celsius and 745MM HG. If the mass of the gas is 0.347G what is the molar mass of the vapor

The molar mass of the vapor comes out to be 43.83 g/mol. This problem is solved by using ideal gas equation. The ideal gas equation is shown below

Explanation:

Volume of gas = V = 247.3 mL  

V = 0.2473 L

Pressure of gas = P = 745 mmHg

1 atm = 760 mmHg

Temperature of gas = T = 100 = 373 K

Given mass of gas = m = 0.347 g

Assuming molar mass of gas to be M g/mol

Assuming the gas to be an ideal gas, the ideal gas equation is shown below

Here, n is the number of moles of gas and R is the universal gas constant.

Hence, the molar mass of the vapor comes out to be 43.83 g/mol

answer; i do believe the correct answer is (river); /// good luck

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
