25.0℃ 1.00 atm 6.618 g 2.00 L mol mass
A certain nonmetal reacts with hydrogen at 440℃
to form a poisonous, foul-smelling gas.
A sample with a mass of 6.618 g was found
to have a volume of 2.00 L at 25.0℃ and 1.00 atm.
What is the molecular weight of the gas?
기체의 밀도 = 6.618 g / 2.00 L
= 3.309 g/L
M = dRT / P
( 참고 https://ywpop.tistory.com/2933 )
= (3.309) (0.08206) (273.15+25.0) / (1.00)
= 80.96 g/mol
답: 80.96 g/mol
(3.309) (0.082) (273+25.0) / (1.00)
= 80.86
≒ 80.9 g/mol
