To get the vapor pressure of the resulting solution, we use
the Raoult’s Law:
Psolution = (χsolvent) (P°solvent)
1st: Calculate the mol fraction of the solvent.
In this case, water is the solvent.
χsolvent = 3.7 mol / (3.7 mol + 0.6 mol)
χsolvent = 0.86
<span>2nd: Calculate the
vapor pressure.</span>
Psolution = (0.86) (23.8 torr)
Psolution<span> = 20.48 torr</span>
Answer:
The total magnification will be 40x.
Explanation:
As we know if the magnification of the eyepiece of a microscope be 
and that of the objective be 
, then the total magnification is given by
Given, 
and 
Therefore total magnification is 
In contrast to quiet eruptions, other volcanoes erupt explosively. Mount St. Helens, for instance, spewed lava high in the air when it erupted. Two things control the type of eruption: how much water vapor and other gasses are in the magma and whether the magma is basaltic or granitic. Basaltic magma tends to ooze out gently in a thin, quiet eruption, while granitic magma is thicker and becomes trapped inside the volcano's vents. Once the pressure grows enough to force out the magma, it explodes.

Answer:primary,secondary and surface waves I do believe
Explanation:
Answer:
708.3 Hz
Explanation:
For an open-air column, like the empty can, the fundamental frequency is given by
where
v = 340 m/s is the speed of sound
L is the length of the column
In this problem, the length of the bottle is
L = 24 cm = 0.24 m
Therefore, the fundamental frequency is
