Answer: 1 mole of the substance is equal to its molar mass or vice versa.
Explanation: Example: 18 g H2O x 1 mole H2O / 18g H2O = 1 mole H2O
You could boil away the water, evaporating it, and leaving behind the solute.
Answer:
: 0.5 atm and
: 1 atm
Explanation:
In order to calculate the partial pressure for each gas , all you need to do is multiply the mole fraction of each gas with the total pressure.
It is given that
= 1.5 atm
The mole fraction of each gas can be calculated in the following way:
= moles of
÷ total moles present = 
= moles of
÷ total moles present = 
Partial pressure of
: 1.5 ×
= 0.5 atm
Partial pressure of
: 1.5 ×
= 1 atm
Hope that answers the question, have a great day!
Answer:
