Answer:
0.3 Meters = 300 Millimeters
Explanation:
Multiply the length value by 1000
Hopefully, this helps! :D
The strong Base with a pH of 12 is reduced by 4 units upon being added with solution Y. If you added a strong acid to the strong base, all ions are present in the solution, yes? So every OH- is neutralised by every H+ for example, meaning the resultant pH should be 7. The resultant pH is only 8 however, so solution Y must be a <em>weak acid </em>only!
Answer : The volume of water added are, 15 mL
Explanation :
Formula used :

where,
are the initial molarity and volume of HCl.
are the final molarity and volume of water.
We are given:

Putting values in above equation, we get:

Hence, the volume of water added are, 15 mL
The answer is D: Salt and Water
