Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that the gas equation is given as
so here we know that
Now in order to find the final volume we have
Part b)
Work done in this process is given as
46.6666 that is the mass number
Explanation:
14 divided 3.0
If you have a ream of notebook paper available, you can measure the height of the stack and divide that by the number of sheets in the ream.
Or you can look up the average density of notebook paper, measure the mass of the sheet, then find the volume by dividing its mass by its density. Then divide the volume by the length and width of the sheet.

15.C Mucus reduces friction
Three of these are strong electrolytes:
- HCl (Hydrochloric acid)
- HNO3 (Nitric acid)
- NaOH (Sodium hydroxide)
Two of these are Weak electrolytes:
- HF (Hydrogen fluoride)
- HC2H3O2 (Acetic acid)
And the other two are Non-electrolytes:
- C6H12O6 (Glucose)
- C2H5OH (Ethanol)
