What volume of argon gas is equal to 1.60 grams of argon
Novosadov [1.4K]

Answer:

0.908 L.

Explanation:

  • Firstly, we should calculate the number of moles of 1.60 g argon.
  • n of Ar = mass / molar mass of Ar = (1.60 g) / (39.948 g/mol) = 0.04 mol.
  • |t is established  and known that the molar volume of a gas at STP (Standard Temperature and Pressure) is equal to 22.4 L for 1 mole of any ideal gas at a temperature of 273.15 K and a pressure of 1.00 atm.

<u><em>using cross multiplication:</em></u>

1.0 mole of Ar gas will occupy → 22.7 L

0.04 mole of Ar gas will occupy → ??? L

∴ The volume  occupied by Ar = (0.04 mole) (22.7 L) / (1.0 mole) = 0.908 L.

Click on the graph to show the correct relationship between altitude and boiling point
spin [16.1K]

Explanation:

This graph shows that an increase in altitude causes a relative decrease in  boiling point temperatures. The two variables, it can be said, are inversely proportional.

This is because, with an increase in altitude, there is a proportionate decrease in air pressure. This means the vapor pressure of the fluid becomes strong enough, at a relatively lower temperature, to overcome the air pressure and for the liquid to boil.

This is why water can even boil without inputting heat into it but rather by just reducing the ambient air pressure.
