Calculate the volume occupied by 250 moles of water vapor at STP, assuming ideal gas behavior.

If 90 g of water is converted to steam at STP and behaves ideally, what volume will it occupy?

How many moles of water vapor are present in 5600 L at STP?

A container holds 4.5 kg of water. If all the water is converted to steam at STP and assumes ideal gas behavior, which is closest to the container's volume?

The volume occupied by 8gm of oxygen at S.T.P is
