Answer:
n = 0.0022 mol
Explanation:
Moles is denoted by given mass divided by the molar mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molar mass .
From the information of the question ,
w = 0.108 g
As we known ,
The molar mass of titanium = 47.867 g / mol
The mole of titanium can be caused by using the above relation , i.e. ,
n = w / m
n = 0.108 g / 47.867 g / mol
n = 0.0022 mol
Answer:
c. a question or problem statement
You need to monitor the solution to see when the crystals start gathering at the bottom of the solution. You can slowly add alum until it stops dissolving. The point just before it starts its sedimentation at the bottom is the point when the solution is saturated.
Answer:
Explanation:
Hydrogen has 1 proton and one nuetron
Oxygen has 8 protons nad 8 neutrons
There are 600 hours.
explanation
each day has 24 hours and we want to know how much hours is equivalent to 25 days so we multiply 24 times 25 which is 600.
