A sample of hydrogen gas occupies 14.1 L at STP. How many moles of the gas are present?

1 Answer

Answer:

#0.63 mol#

Explanation:

For gases at STP, the molar volume equation/relationship can be used where 1 mol of gas occupies 22.4 L of volume.

Therefore,
#14.1cancelL \cdot (1mol)/(22.4cancelL) = 0.6294642857143 mol #
