Molarity is defined as the ratio of number of moles to the volume of solution in litres.
The mathematical expression is given as:
Here, molarity is equal to 1.43 M and volume is equal to 785 mL.
Convert mL into L
As, 1 mL = 0.001 L
Thus, volume = 
= 0.785 L
Rearrange the formula of molarity in terms of number of moles:
n = 
= 1.12255 mole
Now, Number of moles = 
Molar mass of potassium hydroxide = 56.10 g/mol
1.12255 mole = 
mass in g = 
= 62.97 g
Hence, mass of 
= 62.97 g
A 1-liter bag of IV solution would contain how many cubic centimeters of fluid?
1000 cc
Answer:
Explanation:
10.11 g sample of 
contains 22.34% 
by mass
According to the law of constant composition the if one sample of has 22.34% of by mass then any other sample of will have the same percentage of the amount of .
For a sample of 7.09 g we have
The mass of sodium in the required sample is .
Answer:
The events in the rock cycle can be divided into categories:
a) Surface Events
These are the changes that occur on the surface of the earth. This includes weathering and erosion
Igneous Rocks
b) Subsurface Events
These are the changes in the cycle that occur in the inner surface of our planet. This is under the surface of Earth. This includes process like plate tectonics and mountain building.
Sedimentary
