Answer:
0.067 M
Explanation:
Given data:
Volume of solution = 1.00 L
Mass of BaCl₂ = 14 g
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will calculate the number of moles first.
Number of moles = mass/ molar mass
Number of moles = 14 g/ 208.23 g/mol
Number of moles = 0.067 mol
Now we will calculate the molarity.
Molarity = 0.067 mol / 1.00 L
Molarity = 0.067 M ( mol/L=M)
Answer:
33
Explanation:
as the atomic number states the number of protons in each element hope this helps :)
Answer:
the element is fluorine
Explanation:
for the future, add up the little dots- which are electrons and the total of the dots is the atomic number, the little number on the periodic table.
Answer:
There are many opportunities a chemist, chemical engineer, and molecular biologist may have. These professions and or practices could become Product Development Scientists, a Clinical Pharmacist, a Biochemist, or a Pharmaceutical Administer. These careers are very important, because people with professions in these areas will be able to get well paying jobs that will most likely have increasing value over time.
Schools need to offer chemistry so people seeking jobs in these areas will be able to do what they love, and for those who are seeking other science related professions like becoming nurses and other important members in the work force, will be able to get the education they need. Chemistry is a college level class, and is a college credit. If you're not seeking a higher profession in the scientific area, you can take it to get a required credit out of the way.
There are a plethora of science jobs out there that are crucial to the wellbeing of people, and these jobs will ALWAYS be important.
This isn't five minutes... but I hope this helps a little. Add a lil' bit more, and you should be good. I really hope this helped.
