Answer:
60 g/100 g water
Explanation:
Find 5 °C on the horizontal axis.
Draw a line vertically from that point until you reach the solubility curve for CaCl₂.
Then draw a horizontal line from there to the vertical axis.
The solubility of CaCl₂ is 60 g/100 g water.

A. height of the liquid above the point
Answer:
E= 3.829 x 10-16 J
Explanation:
Data Given
Frequency= 5.78 x 10^17 Hz
Energy in joules = ?
Solution:
Formula used to calculate Energy
E= hv…………….. (1)
Where E is Energy
h is Planks Constant = 6.626 x 10–34 J s
v is frequency
The given frequency is in Hz (Hertz)
Hz is equal to s-1 (per second)
1 hertz = 1 /second
Putting the values in Equation 1
E= (6.626 x 10–34 J s) (5.78 x 1017 s-1)
E= 3.829 x 10-16 J
6 protons, 6 neutrons, and 5 electrons
