use the equation PV=nRT and solve the problem
Answer:
The answer is
<h2>32 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 40 mL
density = 0.80 g/mL
The mass is
mass = 40 × 0.8
We have the final answer as
<h3>32 g</h3>
Hope this helps you
Answer:
The increasing order of masses of molecule ions:
118 g/mol(75.8%) , 120 g/mol(24.2%)
Explanation:
Chlorine occurs as 35-Cl (75.8%) and 37-Cl (24.2%).
Atomic mass of 35-Cl = 35 g/mol
Atomic mass of 37-Cl = 37 g/mol
Mass of Chlorocyclohexane in which 35-cl is present as a chlorine atom:
Mass of Chlorocyclohexane in which 37-Cl is present as a chlorine atom:
The increasing order of masses of molecule ions:
118 g/mol(75.8%) < 120 g/mol(24.2%)
Answer : The vapor pressure of the dry oxygen gas is, 736.2 torr
Explanation : Given,
Volume of sample of oxygen = 500 mL
Vapor pressure of oxygen + water = 760 torr
Vapor pressure of water = 23.8 torr
Now we have to determine the vapor pressure of the dry oxygen gas.
Vapor pressure of the dry oxygen gas = Vapor pressure of (oxygen + water) - Vapor pressure of water
Vapor pressure of the dry oxygen gas = 760 torr - 23.8 torr
Vapor pressure of the dry oxygen gas = 736.2 torr
Thus, the vapor pressure of the dry oxygen gas is, 736.2 torr
