Explanation:
It is given that the initial mass of benznene is 7.9286 g
Mass of benzene left = 5.9987 g
So, mass of benzene with which gas get saturated will be calculated as follows.
= 7.9286 g - 5.9987 g = 1.9299 g
Therefore, moles of benzene with which gas get saturated =
=
= 0.0247 moles
Temperature =
= 27.3 + 273.15 = 300.45 K
Volume = 5.01 L
So, according to ideal gas equation PV = nRT
Putting the given values into the ideal gas equation as follows.
PV = nRT
= ![0.0247 mol \times 62.36 torr-liter/mol K \times 300.45 K](https://tex.z-dn.net/?f=0.0247%20mol%20%5Ctimes%2062.36%20torr-liter%2Fmol%20K%20%5Ctimes%20300.45%20K)
P = ![\frac{462.781 torr-liter}{5.01 L}](https://tex.z-dn.net/?f=%5Cfrac%7B462.781%20torr-liter%7D%7B5.01%20L%7D)
= 92.371 torr
Hence, we can conclude that vapor pressure of benzene is 92.371 torr.
The candy coating of the M&M is made of sugar and colored dye. When water comes into contact with the sugary coating, the positive and negative charges in the water molecules pull on the negative and positive charges in the sugary coating, and the coating dissolves.
Answer:
a
Explanation:
most of the world is made of water because the oceans.
If heat flows into the surroundings, the random motions of the molecules in the surroundings increase. Thus, the entropy of the surroundings increases. The second law of thermodynamics states that the total entropy of the universe always increases for a spontaneous process.
