The new lowered freezing point of the benzene mixture is determined as 2.4°C.
<h3>
Effect of impurities in freezing point</h3>
The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.
Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C
New freezing point = 5.5°C - 3.1°C = 2.4°C
Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

Answer:
The location of the electrons in the Thomson's plum pudding model of the atom are contained in orbitals. These orbitals are what make the element stable or unstable
Answer:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 104 kPa
= final pressure of gas = 52 kPa
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
To calculate your weight in Newton's simply use the following equation to solve for the weight.
Fg = m • g
Fg = 60 kg • 9.81 m/s^2
Fg = 588.6 kgm/s^2
Fg = 588.6 N.
Acceleration due to gravity on earth is 9.81 m/s ^2.
Answer:
63.6%
Explanation:
The given compound is:
N₂O;
The problem here is to find the percent composition of nitrogen in the compound.
First find the molar mass of the compound:
Molar mass of N₂O = 2(14) + 16 = 44g/mol
So;
Percentage composition of Nitrogen = x 100 = 63.6%
