On the periodic table it shows the molecular weight of all the elements and what you do is add all the numbers together:
CaCl2=40.08+35.45x2=110.98g/mol
*Ca(NO3)2=40.08+14.01x2+16x6=164.1g/mol
*Ca(OH)2=40.08+16x2+1.008x2=74.096g/mol
CaSO4=40.08+32.06+16x4=136.14g/mol
BaCl2=137.33+35.45x2=208.23g/mol
*these 2 require you to distribute the 2 into each of the elements.

If you want to measure a volume of 8 microliters that could be done with two different micropippetors (the 1-10 uL or 2-20 uL).
Soloha48 [4]

Hey There!

You should choose 1-10 uL pipette !  

Small range  measurement scales are more efficient than large range scale because they give more accurate measurement as they have visible marks on it  small for all measurement.

Q 1 : why are cylinders of oxygen used in hospitals?
svetlana [45]

Answer:

A)provide a basis for virtually all modern anaesthetic techniques

restore tissue oxygen tension by improving oxygen availability in a wide range of conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest

aid resuscitation

provide life support for artificially ventilated patients

aid cardiovascular stability

B)Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. ... Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal.
