A sample of an unknown compound is vaporized at 110. °C. The gas produced has a volume of 2280. mL at a pressure of 1.00 atm, and it weighs 3.66 g. Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Round your answer to 3 significant digits. mol

A sample of an unknown compound is vaporized at 110. °C. The gas produced has a volume of 2280. mL at a pressure of 1.00 atm, and it weighs 3.66 g.
Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Round your answer to 3 significant digits.

O GASES
Using the combined gas law
For many purposes we can treat butane (C,H10)
as an ideal gas at temperatures above its boiling point of -1. °C.
Suppose the pressure on a 71.0 g sample of butane gas at 37.0°C is tripled.
O yes
Is it possible to change the temperature of the 'butane at the same time such that
the volume of the gas doesn't change?
O no
If you answered yes, calculate the new temperature of the gas. Round your
answer to the nearest °C.
