Solution: At STP, what is the mass 13.0 L of methane, CH 4?a. 0.580 gb. 16.0 gc. 9.31 gd. 27.6 ge. 22.4 g

Problem

At STP, what is the mass 13.0 L of methane, CH 4?

a. 0.580 g

b. 16.0 g

c. 9.31 g

d. 27.6 g

e. 22.4 g

Solution

We are asked to determine the mass of CHat STP


Recall that the standard temperature is at 273 K (0°C) and the standard pressure is at 1 atm. With this information, we shall use the ideal gas equation to determine the number of moles of CHand consequently the mass.
