Question

How many grams of gas are present in 75 L of CH4 at STP?

Answer 1

One mole of an ideal gas occupies 22.414 liters at STP. Assume methane is an ideal gas and figure out how many moles in 75 liters. Then multiply that by the molecular mass of methane and you have your answer. Your answer should be a little more than 50,,,,,,,,,,,,,

Answer 2

Desirae, are you going to do any of your homework yourself?

What you need to do here determine how many moles of methane (CH4) you have [use the ideal gas equation solving for n]. Then multiply the number of moles by the molecular weight for methane.
