Calculate the volume occupied by 55.5 moles of water at STP.

Chemistry
1 answer:
Tems11 [23]3 years ago
4 0

Answer:

Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.

Explanation:

1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).

So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.).   :-)

Answer:

the blanket of gases that surrounds Earth and some other planets

Explanation:

The best definition of the atmosphere is that it is a portion of the earth that is a made up of a blanket of gases.

  • The atmosphere is not peculiar to the earth alone, some other planets also have atmospheric cover.
  • The earth's atmosphere is divided into many different layers.
  • The weather we see and experience on the earth surface is conditioned within the troposphere.
  • This troposphere is the closest layer to the surface.
